What “altermagnetism” means

Wikipedia

In condensed matter physics, altermagnetism is a type of persistent magnetic state in ideal crystals. Altermagnetic structures are collinear and crystal-symmetry compensated, resulting in zero net magnetisation. Unlike in an PT-symmetric collinear antiferromagnet, the electronic bands in PT-non-symmetric antiferromagnets (altermagnets) are not Kramers degenerate, but instead depend on the wavevector in a spin-dependent way due to the intrinsic crystal symmetry connecting different magnetic subla
