High-entropy alloys (HEAs) have attracted much attention due to their excellent mechanical properties, heat resistance, corrosion resistance, and irradiation resistance, but most of the research has been directed toward their application as structural materials. HEA has the potential to exhibit excellent electromagnetic functions that are not found in conventional alloys. In particular, new applications of HEA materials are expected to be developed by applying the fabrication method of nanoscale highly structurally controlled nano-layered thin films, which is a specialty of the spintronics field. In this study, we focus on FeNiCoCuPd alloys, which exhibit Curie temperatures higher than room temperature, and report on the fabrication and magneto-transport properties of these thin films.
