Phase transition in a magnetic field in V2-yO3 (y=0 and 0.04)
arXiv:cond-mat/0012297 · doi:10.1103/PhysRevB.63.052410
Abstract
The effect of a magnetic field on the two long-range-ordered magnetic phases, the collinear insulating antiferromagnetic (AFI) and the incommensurate metallic transverse spin density wave (SDW), is investigated for the vanadium sesquioxide system. A field of 18 T has little effect on the AFI phase of a nominal V2O3 sample. The transverse SDW phase of V1.96O3 can be suppressed by a 4.6(3)-T magnetic field applied in the plane of spiraling spins, while the same magnetic field applied along the spiral axis has little effect on the SDW phase.
