Magnetic resonance in a gallium-doped Cu–Cr–S structure

A layered Cu–Cr–S structure doped with Ga ions and consisting of single-crystal CuCrS$_{2}$ layers, embedded with thin plates of spinel phases CuCr$_{2}$S$_{4}$ and CuGa$_{x}$Cr$_{2-x}$S$_{4}$, has been studied using the magnetic resonance and magnetic susceptibility methods. The Curie temperature and the saturation magnetization of the spinel phases of the samples have been determined. The spinel phase layer thickness has been estimated.
