Abstract
The nuclear magnetic susceptibility of solid was measured between temperatures of 5.3 and 800 mK for several molar volumes. In each case, the susceptibility followed a Curie-Weiss law with a negative Weiss constant, hence a negative exchange interaction . Magnitudes of as a function of molar volume agree with previous measurements.
