Importance of tetrahedral coordination for high-valent transition metal oxides: YCrO${}_4$ as a model system

A. A. Tsirlin, M. G. Rabie, A. Efimenko +3

We have investigated the electronic structure of the high oxidation state material YCrO${}_4$ within the framework of the Zaanen-Sawatzky-Allen phase diagram. While Cr${}^{4+}$-based c…
