The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The reading

This paper reports that in thin films of the high-temperature superconductor YBa2Cu3O7−x (YBCO), rotating a magnetic field of 8 T in the plane of the film at 88 K produces an anisotropic magnetoresistance greater than 1000% and a planar Hall resistance close to 1 Ω. The angular symmetries (cos²(φ) and sin(φ)cos(φ)) are the ones seen in ferromagnets, but YBCO is not ferromagnetic and the signals vanish in the normal state. The paper argues that both effects come from quasiparticles that become spin-polarised through Zeeman splitting near the superconducting transition and then scatter anisotropically because of strong spin-orbit coupling. It also reports nonlinear, current-direction-dependent Hall and magnetoresistance signals consistent with spin-polarised transport. If correct, the findings overturn the long-held assumption that spin-orbit coupling is negligible in centrosymmetric cuprates and open a route to superconducting spintronics operating near liquid-nitrogen temperature.

What carries the argument

The central mechanism is the spin-polarised quasiparticle. Near Tc, an in-plane magnetic field Zeeman-splits the quasiparticle density of states, populating spin-polarised quasiparticles; strong spin-orbit coupling then produces anisotropic scattering whose angular symmetry is cos²(φ) for the longitudinal resistance and sin(φ)cos(φ) for the planar Hall resistance. A second ingredient is the phenomenological saturation law Rxy = nQP/(1 + exp(H1/(H + H0))), which ties the Hall amplitude to the field-induced quasiparticle density, and the model of a Rashba-type intrinsic field that gives the nonlinear, unidirectional resistance components.

What would settle it

Measure, on the same films, the in-plane and out-of-plane upper critical fields (or the resistive transition width as a function of field angle), and compare the angular width of the low-resistance state with the anisotropy of the transition; if the width tracks the anisotropic Hc2 rather than the quasiparticle population, the SOC interpretation fails. Alternatively, rotate the in-plane field with current along two perpendicular crystallographic directions: an SOC origin should rotate the sin/cos patterns with the current axis, while a transition-anisotropy artifact would follow the film plane.

Extended reading notes

Core claim

The paper's central claim is that YBCO, a centrosymmetric cuprate long thought to have negligible spin-orbit coupling, shows transport signatures of strong SOC near its superconducting transition: at 88 K and 8 T, the longitudinal resistance varies with the in-plane field angle as cos²(φ) with an anisotropy exceeding 1000%, while the transverse planar Hall resistance shows sin(φ)cos(φ) behaviour close to 1 Ω. These signals appear only at the onset of superconductivity, peak exactly at the end of the transition, and vanish in the normal state. The paper interprets them as spin-polarised quasiparticle transport: an in-plane field Zeeman-splits the quasiparticle density of states, and strong SOC with spin-momentum locking converts that spin polarisation into anisotropic longitudinal and transverse resistances. It also reports nonlinear, current-direction-dependent Hall and magnetoresistance components with cos(φ) and sin(φ) angular forms, which it models through a Rashba-like intrinsic field. The conclusion is direct experimental evidence of SOC in YBCO and a route towards superconducting spintronics at liquid-nitrogen temperatures.

Load-bearing premise

Everything hangs on the assumption that the sharp resistance drop for fields nearly in the film plane comes from spin-polarised quasiparticle scattering, rather than from the well-known anisotropy of layered YBCO's superconducting transition in a magnetic field.

Editorial extensions

If this is right

  • Spin-orbit coupling must be added to the physics of cuprate superconductors, at least near the transition, where quasiparticle transport is sensitive to spin texture.
  • The planar Hall effect and anisotropic magnetoresistance provide a contact-level probe of quasiparticle spin polarisation without requiring a ferromagnet or proximity junction.
  • The effects can be tuned by oxygen doping, film thickness, temperature, and magnetic field, suggesting that spin-dependent transport in YBCO is controllable.
  • The observed nonlinear, unidirectional resistance components make YBCO a candidate for studying nonreciprocal transport and possibly nonreciprocal superconducting spintronics.
  • Because the signals appear near 88 K, the effect operates in a practically accessible temperature window for liquid-nitrogen-cooled devices.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • If the SOC interpretation is right, spin-polarised quasiparticles should be detectable by nonlocal spin-transport experiments, such as spin injection through a YBCO channel, which would provide an independent test beyond the resistance measurements.
  • Because the planar Hall effect is the transverse counterpart of any angle-dependent longitudinal resistance, a clean comparison would be to measure a layered superconductor with similar upper-critical-field anisotropy under the same protocol, since a pure anisotropy artifact would reproduce the effect while an SOC origin would not.
  • The sign reversal of the nonlinear Hall signal with temperature and doping maps naturally to the helicity of spin-momentum locking, offering a potential transport-based readout of cuprate spin texture across the phase diagram.
  • Extending the measurements to underdoped films, where the superconducting window broadens, could reveal how the quasiparticle recombination lifetime controls the magnitude and angular width of the effect.

Referee Report

4 major / 4 minor

Summary. The manuscript reports angular-dependent longitudinal and transverse resistances in YBCO thin films measured near the superconducting transition (88 K, 8 T), including an in-plane anisotropic magnetoresistance in excess of 1000%, a planar Hall resistance of order 1 ohm, and nonlinear current-dependent Hall signals. The authors attribute these observations to spin-polarized quasiparticle transport and strong spin-orbit coupling, and they claim direct experimental evidence of SOC in a cuprate superconductor. Additional measurements as functions of temperature, magnetic field, film thickness, and doping are presented to support the proposed picture.

Significance. If the interpretation were correct, the work would be significant for superconducting spintronics and for the current understanding of spin-orbit coupling in cuprates. The experimental data are systematic, the figures are clear, and the paper explicitly connects its observations to recent spin-resolved photoemission results in bismuth-based cuprates. However, the central claim is not established: the measurements are performed inside the superconducting transition, and a conventional baseline, namely the anisotropic upper critical field of a layered superconductor, is neither modeled nor excluded. The transverse signal may also be contaminated by contact misalignment in the presence of a very large angle-dependent longitudinal resistance. The raw observations are potentially interesting, but the claimed SOC evidence is not supported by the analysis as presented.

major comments (4)
  1. [Fig. 3b and 'Sample description and planar Hall effect measurements'] The sharp drop in Rxx when the field is within about 10 degrees of the film plane is the expected signature of the anisotropic upper critical field of layered YBCO, where Hc2_ab is much larger than Hc2_c. At 88 K and 8 T, for most out-of-plane angles the perpendicular field component exceeds Hc2_c, driving the film into a high-resistance state, while for angles near theta = 90 degrees and 270 degrees the perpendicular component drops below Hc2_c and the film becomes superconducting. The manuscript does not measure Hc2(theta) for these films and does not fit or subtract an anisotropic Ginzburg-Landau or effective-mass model. Therefore the observed angular dependence of Rxx cannot be attributed to spin-orbit coupling without first excluding this textbook mechanism.
  2. [Fig. 1d and 'Sample description and planar Hall effect measurements'] The planar Hall signal of order 1 ohm is measured in a geometry in which the longitudinal resistance varies by more than 1000% with angle. Under these conditions, a small contact offset in the Hall bar can mix a fraction of the large angle-dependent longitudinal resistance into the transverse channel, producing a spurious signal with the observed sin(phi)cos(phi) symmetry. The manuscript does not report antisymmetrization with respect to field reversal or current reversal, nor does it quantify the contact misalignment. The existence of an intrinsic planar Hall effect is therefore not established.
  3. [Fig. 2d and field-dependence fits] The field dependence of Rxy is fitted with the three-parameter expression Rxy = nQP/(1 + exp(H1/(H + H0))). This is a generic sigmoid and can describe many smooth saturation curves, including the ordinary field-induced suppression of superconductivity in the transition region. The parameters nQP, H1, and H0 are not independently determined by any spin-orbit or quasiparticle model, so the quality of the fit does not provide evidence for spin-polarized quasiparticles or strong spin-orbit coupling.
  4. ['Signatures of the spin-orbit coupling'] The sign reversal of the nonlinear Hall signal R_NL_xy is rationalized by invoking doping-dependent helicity from reference [24], but no spin-texture measurement or microscopic calculation for YBCO is provided. This is a post hoc explanation rather than a tested prediction. Moreover, the manuscript itself describes the model as 'a simplistic model' and states that 'further studies are required'. This language is inconsistent with the abstract's claim of 'direct experimental evidence of SOC in YBCO', and it further weakens the central conclusion.
minor comments (4)
  1. [Fig. 1d] The figure axis and the text do not make explicit whether the plotted quantity is the raw Rxx or a normalized anisotropic magnetoresistance ratio. If AMR is defined as [R(phi)-R_min]/R_min, the definition should be stated in the caption or text.
  2. [Fig. 4a] The label 'AHE dips' is misleading for a non-magnetic superconductor; the sign-reversing Hall effect observed near Tc is not an anomalous Hall effect in the conventional sense. Consider using a term such as 'Hall-sign-reversal dips'.
  3. [Methods and device fabrication] A dc current of 5 mA is applied to Hall bars with widths of 20-50 microns and thicknesses down to 15 nm. This corresponds to a large current density, and current-induced heating or phase-slip processes near Tc could affect the measured nonlinear signals. The authors should comment on current-density checks or show that the signals are independent of current.
  4. [Throughout] The text repeatedly refers to 'a typical YBCO device' for the central results. The number of measured devices and the device-to-device variation should be reported, especially for the doping and thickness comparisons in Fig. 4.

Circularity Check

The PHE field dependence is a fitted phenomenological sigmoid whose amplitude is named nQP ('saturation density of spin-polarised quasiparticles'); this fitted parameter is then presented as direct evidence for spin-polarised quasiparticle transport and SOC, making the central claim partially circular by construction.

  1. fitted input called prediction [Section 'Sample description and planar Hall effect measurements', discussion of Fig. 2d; conclusion repeated in 'Summary and outlook']
    "This behaviour can be modelled by fitting a phenomenological equation of the form Rxy = nQP/(1 +exp(H1/(H +H0))) with the assumption that PHE arises due to spin-polarised quasiparticles, as discussed later. In this context, nQP represents the saturation density of spin-polarised quasiparticles."

    The field dependence of the PHE is not derived from spin-orbit coupling or from the quasiparticle picture; it is a generic three-parameter sigmoid fitted to the same data. The fit amplitude is named nQP, the 'saturation density of spin-polarised quasiparticles,' and this named parameter is then used to support the proposal that PHE is caused by spin-polarised quasiparticles and, in the Summary, to announce 'direct experimental evidence of SOC in YBCO.' In other words, the evidence for spin-polarised quasiparticles is the fitted amplitude of a curve that was assumed to represent them; no independent prediction is made. The paper's own qualification that the model is 'simplistic' and that 'further studies are required' underscores that the quantitative link is a named fit, not a derivation.

full rationale

The paper contains no self-citation chain and no uniqueness theorem imported from the authors; the device-orientation control and the external SARPES citations [22-24] are independent. The central circularity is narrower: the only quantitative model connecting the data to spin-polarised quasiparticles is the phenomenological fit Rxy = nQP/(1+exp(H1/(H+H0))), fitted under the explicit assumption that PHE arises from spin-polarised quasiparticles. The fitted amplitude nQP is then presented as evidence for those quasiparticles and for SOC. That is a fitted input renamed as a finding, hence partial circularity. The alternative baseline of anisotropic Hc2 (the sharp resistance drop when the field is within about 10 degrees of the film plane, Fig. 3b) is not modelled or excluded, but that is a correctness/robustness issue rather than a derivation-equivalent circularity, so it does not by itself raise the circularity score further. The nonlinear-sign-reversal explanation borrows an external doping-helicity relation from [24], which is a real external constraint rather than self-citation.

The central claim rests on a set of free parameters, domain assumptions, and a postulated Rashba field. The three sigmoid fit parameters are fitted to the data without reporting values. The Rashba field is invented to explain the nonlinear signals and has no independent evidence. The paper does not introduce a formal derivation, so these entries represent the true cost of the claim.

Spin transport in superconductors offers a compelling platform to merge the dissipationless nature of superconductivity with the functional promise of spin-based electronics. A significant challenge in achieving spin polarisation in conventional superconductors stems from the singlet state of Cooper pairs, which exhibit no net spin. The generation of spin-polarised carriers, quasiparticles, or triplet pairs in superconductors has predominantly been realised in hybrid superconductor/ferromagnet systems through proximity-induced spin polarisation. Historically, cuprate superconductors have been characterised by strong electronic correlations but negligible spin-orbit coupling. Here, we report exceptionally large anisotropic magnetoresistance and a pronounced planar Hall effect arising near the superconducting phase transition in the prototypical high-temperature cuprate superconductor YBa2Cu3O7-x without using a proximity ferromagnet. These effects, unprecedented in centrosymmetric cuprates, emerge from spin-polarised quasiparticle transport mediated by strong spin-orbit coupling. By systematically tuning magnetic field strength, orientation, temperature, and doping, we show clear evidence of spin-orbit-driven transport phenomena in a material class long thought to lack such interactions. Our findings reveal an unexpected spin-orbit landscape in cuprates and open a route to engineer spintronic functionalities in high-temperature superconductors.
