<span>Collinear <em>p</em>-wave magnetism and hidden orbital ferrimagnetism</span>

Author(s): Valentin Leeb and Johannes KnolleIn the absence of spin-orbit coupling, collinear magnets are classified as even-wave magnets, i.e., either ferro-, antiferro-, or altermagnets. It is based on the belief that collinear magnets always feature an inversion-symmetric band structure, which forbids odd-parity magnetism. Here, we show tha…[Phys. Rev.
