摘要：

In an attempt to determine the magnetic moment of vanadium in the proposed antiferromagnetic state in insulating V2O3, the nuclear specific heat has been measured in the temperature range below 0.5 degrees K. A nuclear Schottky anomaly varying with T-2 is observed which indicates an over-all hyperfine splitting of 74 m degrees K and a hyperfine field of 168 kOe. Using a hyperfine coupling constant deduced by Jones from Knight-shift measurements in the metallic state of V2O3, this hyperfine field is consistent with an ordered moment of 1.2 mu(B) per vanadium ion.
