Abstract
High-entropy oxide thin films have recently been introduced as an attractive strategy to design and enhance ferroic properties. Here, the authors perform element-sensitive x-ray absorption spectroscopy and magnetometry on high-entropy oxide perovskite thin films, shedding light on how different transition metal elements contribute to the overall magnetic response. The results demonstrate not only how disorder can lead to enhancement of magnetic properties but also provide a route towards further improvements of other desired properties in corresponding oxide thin films.
