Abstract

We report the magnetic properties of Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O, a high-entropy oxide with a rocksalt structure, and the influence of substitutions on these properties. From the magnetic susceptibility and neutron diffraction measurements, we found that this compound exhibits long-range magnetic order below 120 K despite the substantial structural disorder. Other rocksalt-type high-entropy oxides with various chemical substitutions were found to host either an antiferromagnetic order or spin-glass state depending on the amount of magnetic ions. The presence of magnetic order for such a disordered material potentially provides a route to explore exotic magnetic properties and functions.
