However, there is an important problem in Mn-based Heusler alloys, which is the magnetic compensation phenomenon. Due to the existence of magnetic compensation, the magnetic properties of these alloys are limited in practical applications. Therefore, the study of magnetic compensation effects in Mn-based Heusler alloys and the resolution of the influence of magnetic compensation phenomena on the magnetic properties of this class of materials are of great significance.In this report, we will first introduce the structure and magnetic properties of Mn-based Heusler alloys, and then explain the definition and mechanism of magnetic compensation phenomenon, and summarize previous research achievements. Then, we propose future research directions and prospects, including the search for new Mn-based Heusler alloy materials, the study of magnetic compensation mechanisms, and the exploration of the impact of magnetic 精品文档---下载后可任意编辑compensation effects on other properties. Finally, we discuss the uncertainties and shortcomings in the research in this field.Keywords: Mn-based Heusler alloys; magnetic compensation effect; magnetic properties; mechanism; prospect
