Abstract

Laser molecular-beam epitaxy has been employed to obtain layers of yttrium-iron garnet (YIG) Y₃Fe₅O₁₂ on gallium nitride substrates. It was found that there exists a polycrystalline YIG phase without admixtures of other structural phases. A magnetic anisotropy of films of the “easy-magnetic plane” type was found. The gyromagnetic ratio and the demagnetizing field 4πM_S were calculated.
