An X-ray Study of the Metal–Insulator Transition System Cr2O3 Doped V2O3 [*]
Professor Douglas M.
Cr2O3 doped into V2O3 at only the 1% level changes the system from a paramagnetic metal to a paramagnetic insulator. According to Mattheiss, this effect is not expected based on local density functional (LDF) theory, and he conjectures it is due to a non substitutional site selection of Cr. Also, various theorists have conjectured that the transition could be a percolative variant of a Mott–Hubbard transition, but no model has been suggested. We have shown the following:
