Abstract Direct nuclear demagnetization is used to cool high density solid3He into the magnetically ordered phases. The pressure change in the samples is detected by a capacitive strain gauge. The entropy of the samples is removed by precooling to a temperature of 0.5 mK in a field of 2.5 T. For a bcc sample with a molar volume of 20.10 cm3/mol, two magnetic transitions have been observed. A similar experiment on an hcp sample with a molar volume of 19.65 cm3/mol is being done. Preliminary data indicates no abrupt change in the pressure as observed in the bcc sample.
