Аннотация:The ionic and phase compositions of a nanosized Y2.5Ce0.5Fe2.5Ga2.5O12 ferrogarnet film produced by dual ion-beam sputter deposition on a Gd3Ga5O12 substrate were studied by X-ray powder diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The Y2.5Ce0.5Fe2.5Ga2.5O12 target for film production was manufactured by gel combustion followed by vacuum annealing. X-ray powder diffraction verified the phase homogeneity of Y2.5Ce0.5Fe2.5Ga2.5O12 both in powder and in films and the absence of cerium dioxide impurity. X-ray photoelectron spectra showed Ce4+ ions on the surface of the Y2.5Ce0.5Fe2.5Ga2.5O12 film along with Ce3+.
