Switching of magnetic anisotropy in a fcc antiferromagnet with direction-dependent interactions

Hiroaki Ishizuka, Leon Balents

Open full text 8 citations

Abstract

Exploration of novel phenomena in oxides with strong spin-orbit coupling is one of the hot topics in condensed matter physics. The authors theoretically study the macroscopic magnetic anisotropy induced by fluctuations. By considering a spin model on fcc lattice with direction-dependent interactions, which may serve as an effective model for insulating magnetic oxides with strong spin-orbit coupling, they discover of a novel behavior in spin models with direction-dependent interaction.
