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.

高熵合金 (HEA) 因其独特且有吸引力的结构、物理、化学或磁性能组合而备受关注。与传统合金不同，HEA 包含多种主要元素。HEA 的组成空间是巨大的，并且只研究了极小的部分。磁性 HEA 是传统软磁性金属材料的有前途的替代品，传统软磁性金属材料通常表现出较差的机械性能。我们回顾了磁性 HEA 的发展进展。讨论了合金成分、晶体结构、相分数和加工参数对磁性能的影响。通过先进的实验性高通量技术处理的磁性 HEA，例如增材制造、共溅射、扩散倍数、快速成型、并通过组合计算技术设计，如热力学和相图计算、密度泛函理论、机器学习等。还讨论了传统的加工技术。概述了磁性 HEA 的未来趋势。
