A two-sublattice ferrimagnet undergoes a transition from a collinear to the canted magnetic phase at magnetic field oriented along an easy magnetization direction. In this work, we study the transition by means of the magneto-optical Faraday effect in a thin film of compensated iron garnet (Lu3− xBi x)(Fe5− y−zGa yAl z)O12 grown on the Gd3Ga5O12 substrate. In the immediate vicinity of the compensation temperature, a precursor of the transition with a complex shape was observed. Using a special…

Interface effects in nanometer-thick yttrium iron garnet films studied by magneto-optical spectroscopy
The properties of nanometer-thick yttrium iron garnet (YIG) films are strongly influenced by interfaces. This work employs spectral ellipsometry (SE) and magneto-optic polar Kerr rotation (PKR) to
Inhomogeneuos state of ferrimagnetic film near compensation point
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
Magnetization reversal in YIG/GGG(111) nanoheterostructures grown by laser molecular beam epitaxy
TLDR
Th thin (4–20 nm) yttrium iron garnet layers grown on gadolinium gallium garnet substrates by laser molecular beam epitaxy have shown that in zero magnetic field magnetization lies in the film plane due to both shape and induced anisotropies.
