高熵合金（HEA）由于其独特的结构，物理，化学或磁性的组合而受到高度关注。HEA包含多种主要元素，与常规合金不同。HEA的组成空间是巨大的，只有一个极小的部分已被研究。磁性HEA是一种有前途的替代传统的软磁金属材料，通常表现出较差的机械性能。本文综述了磁性高能电动机的研究进展。讨论了合金成分、晶体结构、相含量和工艺参数对磁性能的影响。磁性HEA处理先进的实验高通量技术，如增材制造，共溅射，扩散倍数，快速成型，并通过组合计算技术，如热力学和相图计算，密度泛函理论，机器学习等设计进行了审查。传统的处理技术也进行了讨论。概述了磁性HEA的未来趋势。
High-entropy alloys (HEA) are of high current interest due to their unique and attractive combination of structural, physical, chemical or magnetic properties. HEA comprise multiple principal elements, unlike conventional alloys. The composition space of HEA is enormous and only a minuscule fraction has been studied. Magnetic HEA are a promising alternative to conventional soft magnetic metallic materials, which typically exhibit poor mechanical properties. We review the progress in the development of magnetic HEA. The influence of alloy composition, crystal structure, phase fraction and processing parameters on the magnetic properties are discussed. Magnetic HEA processed by advanced experimental high throughput techniques such as additive manufacturing, co-sputtering, diffusion multiples, rapid prototyping, and designed via combinatorial computational techniques, such as thermodynamic and phase diagram calculations, density functional theory, machine learning etc. are reviewed. Conventional processing techniques are also discussed. Future trends in magnetic HEA are outlined.
