    | Abstract Scope | High entropy oxides (HEOs), also referred to as multicomponent oxides or compositionally complex oxides (CCOs), have attracted attention due to the tunability of multiple cations on a single site. Since the introduction in 2015 of HEOs stabilized in the rocksalt phase, the high entropy oxide concept has been expanded to various structures, offering a path for the discovery of innovative compounds with unique structure-property relations. However, the intrinsic disorder and highly localized chemical environments of HEOs bring along new challenges. In order to shed light on the complexities associated with multi-cation oxides, we have initiated a systematic study of polycrystalline and single crystalline HEO samples across multiple crystal systems. This work expands the multi-component concept to new compositions and crystal systems and investigates properties of materials across multiple crystal systems, including spinel, perovskite, and Ruddlesden-Popper multi-component materials. |
