Magnetic properties of VSe2: Inferences from the study of metal-rich V1+δSe2 compounds

Abstract

The intrinsic magnetic properties of VSe₂ in the incommensurate and commensurate charge denity wave states have been examined by magnetic susceptibility and NMR observations. VSe₂ synthesized at high temperatures is slightly metal‐rich and since the excess vanadium atoms are magnetic, their contribution to the magnetic properties must be extracted from those intrinsic to VSe₂. This separation has been accomplished by studying a series of materials of the form V_1+δSe₂ (0.01<δ2 and the excess vanadium species.
