Altermagnetic splitting of magnons in hematite ( $α$ -Fe $_{2}$ O $_{3}$ )

Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3

We develop a four-sublattice spin-wave theory for the $g$ -wave altermagnet candidate hematite ( $α$ -Fe $_{2}$ O $_{3}$ ), considering both its easy-axis phase below and its weak ferromagnet…

Spontaneous Crystal Thermal Hall Effect in Insulating Altermagnets

Rhea Hoyer, Rodrigo Jaeschke-Ubiergo, Kyo-Hoon Ahn +2

We show that magnetic insulators with a collinear and compensated order can exhibit a thermal Hall effect even at zero magnetic field if they have altermagnetic symmetries. We pred…
