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, including fluorites, perovskites, and spinels. Here, we report on our recent efforts to engineer new ceramic materials by applying the concept of entropy stabilization to complex oxides. More specifically, by adding the chemical and structural disorder inherent to entropy-stabilized materials to the competing electronic/magnetic interactions that characterize complex oxides, we provide a new strategy for the design/discovery of materials with unique properties. |
