Abstract: Symmetry and hybridization yield anisotropic but nodal-less Fermi surfaces in s-wave ferromagnets (FMs) and antiferromagnets (AFMs), while they produce distinct momentum-space nodes in altermagnets (AMs). Both drive anisotropic femtosecond magnetization dynamics, but this link remains… read more here.
