Abstract

The ionic and phase compositions of a nanosized Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ 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 Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ target for film production was manufactured by gel combustion followed by vacuum annealing. X-ray powder diffraction verified the phase homogeneity of Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ 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 Y_2.5Ce_0.5Fe_2.5Ga_2.5O₁₂ film along with Ce³⁺.

Gd3Ga5O12衬底上Y2.5Ce0.5Fe2.5Ga2.5O12纳米薄膜的离子和相组成

采用x射线粉末衍射（XRD）和x射线光电子能谱（XPS）研究了双离子束溅射沉积在Gd3Ga5O12衬底上制备的纳米Y2.5Ce0.5Fe2.5Ga2.5O12铁石榴石薄膜的离子和物相组成。采用凝胶燃烧-真空退火法制备薄膜用Y2.5Ce0.5Fe2.5Ga2.5O12靶材。x射线粉末衍射验证了Y2.5Ce0.5Fe2.5Ga2.5O12在粉末和薄膜中的相均匀性，不含二氧化铈杂质。x射线光电子能谱显示，Y2.5Ce0.5Fe2.5Ga2.5O12薄膜表面存在Ce4+离子和Ce3+离子。
