Abstract
The effect of a magnetic field on the two long-range-ordered magnetic phase s, the collinear insulating antiferromagnetic (AFI) and the incommensurate metallic transverse spin density wave (SDW), is investigated for the vanadi um sesquioxide system. A field of 18 T has little effect on the AFI phase o f a nominal V2O3 sample. The transverse SDW phase of V1.96O3 can be suppres sed by a 4.6(3)-T magnetic field applied in the plane of spiraling spins, w hile the same magnetic field applied along the spiral axis has little effec t on the SDW phase.
