✦ Synopsis

Nuclear magnetization of solid 3He has been studied by static magnetization measurements from lOmK down to 0.3 mK for molar volumes ranging from V=24.14 to 21.02cm3/mole in the bcc phase and from V= 19.83 to 19.26 cm3/mole in the hcp phase. In the bcc phase, both the antiferromagnetic transition temperature T N and the reciprocal of the maximum magnetization V~x at TN vary in proportion to V 165~I, and the magnetization below TN is constant. The magnetization reduced by Mmax is found to be represented by a universal function of the reduced temperature T/TN. In the hcp phase, the magnetization can approximately be represented by Curie's law, and the estimated Weiss temperatures are below 50 i~K. We also observed that the boundary magnetism of liquid 3He depends considerably~ on pressure. The transition temperature of solid 3He to the antiferromagnetic phase coexisting with liquid in a restricted geometry is 15% higher than that of the bulk solid on the melting curve.

We present results obtained with a setup designed for optical experiments on SHe below 1 inK. The entire optical system is placed inside the vaxuum can of a dilution refrigerator and does not require any windows except for those in the sample cell.

The Peierls inequality combined with a classical Monte Carlo evaluation of the free energy has been applied as a variational technique to the magnetic spin Hamiltonian of 3He. We find unexpectedly good agreement with the experimental phase diagram and other measured quantities. We have applied a ne
