High-entropy Alloys (HEAs), as a new class of materials, have garnered significant attention in the scientific community due to their exceptional mechanical properties, corrosion resistance, and thermal stability. In recent years, researchers have discovered that HEAs not only excel in traditional material applications but also exhibit remarkable magnetocaloric effects, opening up new possibilities for their use in energy conversion and storage. This paper reviews the research advancements in the magnetocaloric effects of high-entropy alloys, including their fundamental principles, preparation methods, and evaluation of magnetocaloric performance at varying temperatures. Furthermore, it explores the key mechanisms related to microstructural factors and element selection that influence the magnetocaloric effects of HEAs. By analyzing existing research findings, this study identifies the current shortcomings and outlines future directions for development, aiming to lay a foundation for further applications of high-entropy alloys in the magnetocaloric field.
