【 摘 要 】

Recent neutron-scattering and nuclear-magnetic-resonance experiments have revealed that the low-temperature phase of doped V2-yO3 is an itinerant antiferromagnet with a helical spin structure. We use a hand-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 lifetime and of dilute magnetic impurities are discussed. [S0163-1829(98)07325-1].
