Recently, high-entropy (HE) materials have attracted increasing interest in various fields due to their unique characteristics. Rare earth (RE) elements have a similar atomic radius and gradually occupied 4f orbitals, endowing them with abundant optical, electric, and magnetic properties. Furthermore, HE-RE materials exhibit good structural and thermal stability and various functional properties, emerging as an important class of HE materials, which are on the verge of rapid development. However, a comprehensive review focusing on the introduction and in-depth understanding of HE-RE materials has not been reported to date. Thus, this review endeavors to provide a comprehensive summary of the development and research status of HE-RE materials, including alloys and ceramics, ranging from their structure, synthesis, and properties to applications. In addition, some distinctive issues of HR-RE materials related to the special electronic structure of RE are also discussed. Finally, we put forward the current challenges and future development directions of HE-RE materials. We hope that this review will provide inspiration for new design ideas and valuable references in this emerging field in the future.
近年来，高熵（HE）材料因其独特的特性在各个领域引起了越来越多的关注。稀土（RE）元素具有相似的原子半径，并逐渐占据4f轨道，赋予它们丰富的光学、电学和磁学性质。此外，高熵稀土材料表现出良好的结构和热稳定性以及各种功能特性，成为一类重要的高熵材料，正处于快速发展的边缘。然而，迄今为止，尚未有一篇全面综述聚焦于高熵稀土材料的介绍和深入理解。因此，本综述致力于对高熵稀土材料（包括合金和陶瓷）的发展和研究现状进行全面总结，涵盖其结构、合成、性能及应用。此外，还讨论了与稀土特殊电子结构相关的高熵稀土材料的一些独特问题。最后，我们提出了高熵稀土材料当前面临的挑战和未来的发展方向。我们希望本综述能为未来这一新兴领域的新设计理念提供灵感和有价值的参考。
