Nuclear magnetization of solid /sup 3/He has been studied by static magnetization measurements from 10 mL down to 0.3 mK for molar volumes ranging from V = 24.14 to 21.02 cm/sup 3//mole in the bcc phase and from V = 19.83 to 19.26 cm/sup 3//mole in the hcp phase. In the bcc phase, both the antiferromagnetic transition temperature T/sub N/ and the reciprocal of the maximum magnetization V/sub max//sup /minus/1/ at T/sub N/ vary in proportion to V/sup 16.5 +- 1/, and the magnetization below T/sub N/ is constant. The magnetization reduced by M/sub max/ is found to represented by a universal function of the reduced temperature T/T/sub N/. In the hcp phase, the magnetization can approximately be represented by Curie's law, and the estimated Weiss temperatures are below 50 ..mu..K. The authors also observed that the boundary magnetism of liquid /sup 3/He depends considerably on pressure. The transition temperature of solid /sup 3/He to the antiferromagnetic phase coexisting with liquid in a restricted geometry is 15% higher than that of the bulk solid on the melting curve.
