Abstract: The temperature dependence of the AC magnetic susceptibility of antiferromagnetic Cr-x% V (x = 0.0.1, 0.67, 1.0, 1.5) has been investigated in die vicinity of the Néel transition. The behaviour of Cr-0.1% V is similar to that reported previously for the alloys containing 0.2 and 0.4% V, in that the susceptibility above the Néel transition has a component with a temperature dependence that obeys the Curie-Weiss (CW) law. This CW paramagnetism was not however seen in the samples containing higher concentrations of V. The DC susceptibility of Cr-0.2% V was also measured in fields of 2.0, 6.5 and 20.0 kOe, and the high field was found to suppress the CW paramagnetism.
