My read agrees and sharpens the point: the 'μB >> 1 ⇒ ONE tends to zero' argument is not valid in a multi-band semimetal, where the ordinary Nernst effect can saturate at a large high-field value. The rotation experiment itself leaves a ≥ 25 μV/K high-field response, which is a lower bound on a possible ordinary component but already sizable relative to the comparison materials in Table 1. The theoretical model for αyx is a two-parameter-per-temperature fit to a classical Lorentz-force expression and therefore does not independently justify the ANE label. This does not undermine the measured total Syx, the thermal Hall angle, or the phase-purity checks; it specifically undermines the 'ANE-dominated' and 'record ANE' wording. A paramagnetic control measurement above TN would settle the matter because the Berry-curvature ANE tied to the canted AFM order should disappear there. Since the paper itself flags the inability to separate ONE from ANE, the appropriate verdict remains CONDITIONAL (unchanged from the reader): the central measurement is credible, but the headline mechanistic claim needs an additional control or a more carefully qualified statement.","tokens_in":21680,"tokens_out":9749,"duration_ms":119426,"concrete_test":"Measure Syx(H) of sample 1 in the same H // [110], jQ // [11̅0], V // [001] geometry at several temperatures spanning TSC ≈ 250 K and TN ≈ 290 K, especially just above TN (e.g., T = 310 K). The canted-AFM order and its Berry-curvature ANE should switch off above TN, so any high-field saturated Syx remaining at T = 310 K is ordinary Nernst. If that paramagnetic saturated value is large (e.g., comparable to or more than half of the ~110 μV/K observed at 254 K), the assumption that ONE is negligible in sample 1 is untenable and the ANE-dominated record claim must be retracted or heavily qualified. If the saturated Syx drops to a small value above TN, the concern is largely resolved. The same comparison should be reported for the 60-degree-rotated configuration to bound the ordinary component.","verdict_should_be":"UNCHANGED","load_bearing_attack":"The central claim is that the ~110 μV/K Nernst thermopower of sample 1 is ANE-dominated and constitutes a record anomalous Nernst thermopower in a magnetic material. The authors explicitly state in Table 1 and Supplementary Table 1 that for sample 1 they cannot reliably separate ANE from the total Nernst thermopower; the main text says Syx is 'presumably with SANE dominant,' and Table 1 argues for SANE > 70 μV/K using the high-field saturation tendency. The stated justification is that in the regime μB >> 1 the ordinary Nernst coefficient 'tends to zero.' That justification is not generally valid for a multi-band semimetal: in compensated or multi-carrier systems, the ordinary Nernst coefficient does not necessarily vanish at high field; it can saturate at a large, material-dependent value, and in nodal-line/Dirac semimetals a large high-field saturated Nernst response is common (cf. refs. 28–29). Thus the saturation seen in Fig. 2a is precisely the regime where ONE can be largest, not where it can be assumed absent. The rotation control in Supplementary Fig. 10b still shows saturated Syx ≥ 25 μV/K after a 60-degree in-plane rotation at T > 250 K, demonstrating a substantial component not tied to the spin-canting direction. The theoretical αyx in Eqs. (S16)–(S22) is a Lorentz-force/ordinary Nernst conductivity model with two fitted parameters per temperature; matching this model does not identify or isolate an anomalous contribution.

The authors argue that this signal is dominated by the anomalous Nernst effect and therefore constitutes the highest ANE-dominated Nernst thermopower in any magnetic material. They also report a thermal Hall angle between 0.02 and 0.06 at 9 T for 40 K < T < 310 K. The interpretation combines the measured Hall conductivity with a fitted Nernst-conductivity model based on a partially filled Weyl band, proposing that the large thermopower arises from a synergy of a classical Nernst conductivity, a topological Hall conductivity, and the strong resistivity anisotropy.","tokens_in":1511,"tokens_out":2552,"duration_ms":93945,"significance":"If the ANE-dominated assignment were established, this would be a substantial advance in transverse thermoelectric materials: it would place YbMnBi2 roughly an order of magnitude above previously reported ANE materials and would identify a concrete design principle involving Fermi-level tuning near Weyl points combined with large resistivity anisotropy. The raw Nernst and thermal Hall measurements are reproducible across two samples, and the rotated-field control in Supplementary Fig. 10 is a thoughtful check against trivial alignment effects.

The authors state in Table 1 that for sample 1 'we cannot reliably separate the ANE from the total Nernst thermopower,' and the estimate SANE > 70 μV/K rests on the assertion that the ordinary Nernst coefficient tends to zero when μB is much larger than unity. That assertion is not generally valid for multi-band or compensated semimetals, where the ordinary Nernst coefficient can saturate at a large, field-independent value (see, e.g., refs. 28–29). The saturation of Syx in Fig. 2a is therefore not by itself evidence of ANE dominance. In fact, the rotated-field control in Supplementary Fig. 10b still shows saturated Syx values of at least 25 μV/K at T > 250 K after a 60-degree in-plane rotation away from [110], which demonstrates a substantial component that is not tied to the spin-canting direction.

The record-ANE claim is not.\n\nWhat's new: two lower-doped YbMnBi2 crystals measured with H along the spin-canting direction [110] give a total Nernst thermopower Syx ~110 μV/K at 254 K between 5 and 9 T, and a thermal Hall angle 0.02–0.06. That is roughly an order of magnitude above the same compound in ref. 17, and the two-sample reproducibility plus the 60-degree rotation control make the raw observation credible. The sample characterization is careful—no Bi or MnBi inclusions, no hysteresis in the paramagnetic regime. The authors also give a clean derivation of the three-term decomposition Syx = (αyx − σyxSxx)/σyy, which is a useful way to think about why the total Nernst thermopower can be large even when αyx itself is modest. Credit where due: the experimental work is careful and the paper is honest about its own limits.\n\nThe soft spot is load-bearing. The headline claim that this is the highest ANE-dominated Nernst thermopower in a magnetic material rests entirely on sample 1, and the paper explicitly says that for sample 1 the ANE cannot be reliably separated from the total Nernst signal. Table 1 estimates SANE > 70 μV/K from the high-field saturation tendency, with the justification that the ordinary Nernst coefficient tends to zero when μB >> 1. That justification is not generally valid in a multi-band semimetal; the ordinary Nernst effect can saturate at a large, material-dependent value, and the paper's own refs. 28–29 are examples of exactly that. The rotation control makes the problem concrete: after a 60-degree in-plane rotation, Syx still saturates at ≥25 μV/K above 250 K, so a substantial part of the signal is not tied to the spin-canting axis. The total Syx measurement stands, but 'ANE-dominated' and 'record ANE' do not.\n\nThe theory also has a circular flavor. The Nernst conductivity αyx is fit with two free parameters (A0, B0) at every temperature, and that same fitted αyx is then fed into Eq. (2) to back-calculate Syx, so the good agreement in Supp. Fig. 5 is partly built in. The model is a reasonable generalization of Kozii-Skinner-Fu and the fitted μ and τ are consistent with the doping story, but it is not an independent prediction. No raw data or code are deposited.\n\nBottom line: this is a solid experimental observation of a large total Nernst thermopower, with an unsupported attribution to ANE. The fix is straightforward—either provide a credible ONE/ANE decomposition or reframe the claim as a large total Nernst effect. I would send it to a serious referee, but the referee should insist on that before the record language survives.","headline":"The total Nernst signal is real and reproducible, but the record-ANE claim rests on an untested assumption about the ordinary Nernst effect; this needs a credible decomposition or a reframed claim before publication.","tokens_in":22657,"tokens_out":3110,"would_cite":false,"duration_ms":35458,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Lower-doped YbMnBi2, with its chemical potential near the Weyl points, has the highest anomalous Nernst thermopower of any magnetic material—about 110 μV/K—thanks to the combined action of classical filled-band transport, topological Hall…","keywords":["anomalous Nernst effect","YbMnBi2","Weyl semimetal","transverse thermoelectrics","thermal Hall effect","Berry curvature","Nernst thermopower","spin canting"],"falsifier":"A decisive check would be to measure the same low-carrier-density, highly anisotropic Fermi surface without broken time-reversal symmetry—for example, a nonmagnetic analogue of YbMnBi2 or a sample in which the Mn spin canting is suppressed by pressure or chemical substitution while the band structure is preserved.
