We have studied the structural and magnetic properties of $\mathrm{Tb}\left({\mathrm{Fe}}_{0.2}{\mathrm{Mn}}_{0.2}{\mathrm{Co}}_{0.2}{\mathrm{Cr}}_{0.2}{\mathrm{Ni}}_{0.2}\right){\mathrm{O}}_3$ (T5BO) high-entropy oxide perovskite (HEOP) thin films. Using synchrotron-based x-ray absorption spectroscopy, employing x-ray magnetic circular dichroism, we performed an element-sensitive study of epitaxial T5BO thin films. The measurements reveal a magnetic multiphase with variable ferromagnetic ordering of all transition metal elements, providing a promising route towards designer ferroic properties in Tb-based HEOP thin films.

Tb(Fe0.2Mn0.2Co0.2Cr0.2Ni0.2)O3高熵氧化物钙钛矿薄膜中的弱铁磁性

我们研究了它的结构和磁性$\mathrm{结核病}\left({铁}_{0.2}{锰}_{0.2}{\mathrm{公司}}_{0.2}{铬}_{0.2}{你}_{0.2}\right){\mathrm{○}}_3$(T5BO) 高熵氧化物钙钛矿 (HEOP) 薄膜。使用基于同步加速器的 X 射线吸收光谱，采用 X 射线磁圆二色性，我们对外延 T5BO 薄膜进行了元素敏感研究。测量结果揭示了一种磁性多相，所有过渡金属元素具有可变的铁磁有序性，为设计 Tb 基 HEOP 薄膜的铁磁性提供了一条有希望的途径。
