Neutron diffraction from stoichiometric and metal-deficient V2O3

Abstract

Neutron diffraction has been used to study two samples of V2O3, one stoichiometric (TM-I150 K) and a second metal deficient (TM-I50 K). In the former, magnetic intensity was observed below the metal-insulator transition at the 32 32 3 reflection as well as at those reflections previously reported by Moon. This intensity is thought to be due to a small magnetic contribution from the oxygen sites. In the latter sample, antiferromagnetic ordering was observed in the metallic phase with a discontinuous change in magnetic intensity at the M-I transition. The magnetic moment for the pure V2O3 specimen agrees with the 1.21/4B value determined by Moon, but the saturation value in the metal-deficient specimen was determined to be only 0.91/4B. © 1981 The American Physical Society.
