Abstract

Recently, an investigation of the Faraday rotation in thin iron garnet film (LuBi)3(FeAlGa)5O12 revealed an unusual “precursor” of transition to a noncollinear phase. It was observed in the vicinity of the compensation temperature. However, this feature cannot be ascribed to the uniform phase transition associated with uniaxial anisotropy. A model for the “precursor” based on inhomogeneous magnetic structure at the substrate-film interface is presented. To interpret the Faraday rotation, two diamagnetic optical transitions attributed to tetrahedral and octahedral iron sublattices are considered.
