THE EFFECTS OF PRESSURE ON THE PARAMAGNETIC–ANTIFERROMAGNETIC TRANSITION OF DYSPROSIUM

Abstract
The shift of temperature with pressure of the paramagnetic–antiferromagnetic phase transition of dysprosium at 177° K has been found to be −(0.55±0.02) × 10−3 deg K/(kg/cm2). Pressure was applied to the substance by compressing the metal between two pistons in a cylinder. The transition point was determined by measuring the magnetic moment of the sample as a function of temperature at various pressures up to 8400 kg/cm2. The results appear to be consistent with current theories of the magnetic properties of dysprosium.
