  Recent neutron scattering and nuclear magnetic resonance experiments have
revealed that the low temperature phase of doped V_{2-y}O_3 is an itinerant
antiferromagnet with a helical spin structure. We use a band structure
calculation as the point of departure to show that these experiments are in
agreement with mean field results for an Overhauser spin-density wave state.
The influences of a finite life-time and of dilute magnetic impurities are
discussed.
