Abstract

We show by neutron diffraction that metallic V2-yO3 develops a spin density wave below T≈ 9 K with incommensurate wave vector q ≈1.7c* and an ordered moment of 0.15μB. The weak ordering phenomenon is accompanied by strong, nonresonant spin fluctuations with a velocity c = 67(4) meV Å. The spin correlations of the metal are very different from those of the insulator and place V2-yO3 in a distinct class of Motte-Hubbard systems where the wave vector for magnetic order in the metal is far from a high symmetry commensurate reciprocal lattice point.
