Phase transitions in pure and Cr-doped V2O3

The (CrxV1_x)203system undergoes two metal-insulator transitions as a function of temperature. In this report, we present elastic and inelastic neutron scattering data on these two transitions for samples with 0%, 1.5%, 3% and 6% Cr concentration and discuss the apparent suppression of magnetism by the intermediate metallic phase in this system.
