abstract

The symmetry requirements for realizing unconventional compensated magnets with spin-polarized bands such as altermagnets have recently been uncovered. The most recent addition to this family of magnets is parity-odd or $p$-wave magnets. We demonstrate that $p$-wave magnets are perfectly compatible with superconductivity due to the spin polarization of their electron bands and that they induce unexpected spin transport phenomena. We first show that $p$-wave magnetism can coexist with conventional superconductivity regardless of the magnitude of the spin splitting. We then predict that $p$-wave magnets induce a charge-to-spin conversion, which can be strongly enhanced by the presence of superconductivity providing a way to probe the coexistence in experiments. Our results open an avenue for material combinations with a synergetic relation between spintronics and superconductivity.

  1. Dynamical Polarization from Hidden Spin and Orbital Textures in p-Wave Magnets

    cond-mat.mes-hall 2026-07 conditional novelty 6.0 of 10

    Optically driven p-wave magnets develop a resonantly enhanced ac spin polarization at the 2J_sd exchange gap and a rectified, polarization-controlled dc orbital polarization invisible to period-averaged treatments.

    cond-mat.supr-con 2025-02 accept novelty 6.0 of 10

    A two-dimensional hybrid of an s-wave superconductor and a p-wave magnet hosts chiral-symmetry-protected flat-band Majorana bound states and a disorder-robust quantized zero-bias conductance peak.

  3. Crossed Andreev reflection in collinear $p$-wave magnet/triplet superconductor junctions

    cond-mat.mes-hall 2025-01 conditional novelty 6.0 of 10

    Collinear p-wave magnet/triplet superconductor junctions are predicted to support a regime of pure crossed Andreev reflection without external magnetic fields.
