Description
Summary: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 a new avenue for material combinations with a synergetic relation between spintronics and superconductivity.
