The results of the investigation of two-layer Fe/Cr systems using the magneto-optical Kerr effect (MOKE) are presented in this paper. The samples were obtained by thermal evaporation in a vacuum with a thickness of individual layers from 2 nm to 50 nm. It was found that the presence of the Cr layer significantly affects the values of the coercivity and the Kerr angle. At a substrate temperature of 450 K, the value of the coercivity is almost half that of the same sample obtained at room temperature of the substrate. In addition, the influence of the order of deposition of layers, as well as the effect of a thin gold protective layer on the parameters measured by the Kerr method, is shown. These studies have shown that the MOKE can be used as an additional method for studying the composition of multilayer systems, granular alloys and spin-valve systems, using specific software methods.

基于 Fe 和 Cr 的两层薄膜体系的磁光特性

本文介绍了利用磁光克尔效应 (MOKE) 研究两层 Fe/Cr 系统的结果。样品是通过在真空中热蒸发获得的，各层的厚度为 2 nm 至 50 nm。发现Cr层的存在显着影响矫顽力和克尔角的值。在 450 K 的衬底温度下，矫顽力的值几乎是在衬底室温下获得的相同样品的一半。此外，还显示了层沉积顺序的影响，以及薄金保护层对 Kerr 方法测量的参数的影响。这些研究表明 MOKE 可以用作研究多层系统组成的附加方法，
