Abstract

A first-order metal-insulator transition at room temperature has been found in Cr-doped $V_{2}$ $O_{3}$ as a function of both Cr concentration and pressure. This is shown to be a Mott transition in which the conduction electrons localize to form the insulator. A generalized phase diagram relating the metallic, insulating, and antiferromagnetic insulating phases is presented.
