磁二向色性光电发射（ Ｍ Ｄ Ｐ Ｅ） 技术是结合光电子能谱和磁二向色性技术的磁学测量方法，近年来已成为研究表面、界面和薄膜等低维体系磁性的重要手段。本文概述了其基本原理和实验方法，着重探讨几种 Ｍ Ｄ Ｐ Ｅ 效应的产生及其理论解释，并介绍了 Ｍ Ｄ Ｐ Ｅ 在磁性过渡金属、稀土金属低维体系中的应用。
Magnetic dichroic photoemission (MDPE) is a magnetic measurement method combining photoelectron spectroscopy and magnetic dichroism. It has become an important method to study the magnetism of low-dimensional systems such as surface, interface and film in recent years . This paper summarizes its basic principles and experimental methods, focuses on the generation and theoretical explanation of several MDPE effects, and introduces the application of MDEP in low-dimensional systems of magnetic transition metals and rare earth metals.
