Meta-Altermagnetism and Enhanced Spin-Splitting

Altermagnets are collinear magnets with zero net magnetization and spin-split electronic bands. Here, we explore whether altermagnetism can exhibit a discontinuous jump, a phenomenon we refer to as meta-altermagnetism. We show that meta-altermagnetism can emerge in 2D systems when magnetic-order-induced band reconstruc...
