Hysteresis near the compensation of a ferrimagnetic garnet film

Abstract Magnetization measurements and observations using Faraday effect were performed on a ferrimagnetic garnet film, around the compensation temperature ( T comp ). Besides the large increase of the domains size close to T comp , field cycles at different temperatures and thermal variations at different fields show the evolution between metastable states: domains, up or down saturated states and ‘spin-flop’ states very close to T comp .
