Abstract
The magnetic behavior of EuTe was investigated under various pressures up to 11.7 GPa and in the temperature range from 1.4 to 30 K by means of uniform magnetization measurements of extremely small samples in a diamond anvil cell. A pressure-induced transition from antiferromagnetic to ferromagnetic ordering was observed at a pressure of about 8 GPa. It was found that, at pressures below 8 GPa, the susceptibility x M/ H at high temperatures increased with pressure due to the development of the ferromagnetic interaction. At pressures just above 8 GPa, χ( T) showed anomalous behavior resulting from strong competition of magnetic interactions below the critical temperature at which spontaneous magnetization appeared. At pressures above 9 GPa, a ferromagnetic phase was established at low temperature and the Curie temperature increased with pressure.
