Abstract Measurements have been made of the pressure of the bcc phase of solid3He at molar volumes from 24.2 to 23.2 cm3 and at temperatures from 25 to 0.5 mK. The solid undergoes an unusual antiferromagnetic ordering at a temperature that depends strongly on the sample density. This ordering is due to the unusually large exchange interaction in solid3He, a factor of 104 stronger than the nuclear dipole-dipole interaction. The large latent heat associated with the first-order transition has constrained the size of the sample. The pressure of 0.005 cm3 of solid3He has been measured while the volume of the experimental cell was regulated to within 15 parts in 106. The results provide information on the magnitudes and molar volume dependences of the exchange rates, and suggest that a single physical process governs all aspects of the ordering transition.
