摘要：

The magnetization M of Sn1-xEuxTe:EuTe, x less than or equal to 0.02, has been measured at 4.2 K in fields H up to 23 T. The average pair exchange interaction is antiferromagnetic with a value of about 0.5 K. For x-values greater than 0.014 the M vs. H curves show a definite knee with approximately linear behavior above and below the knee. The knee in the magnetization data and a cusp in the susceptibility at about 10 K are related to the presence of EuTe clusters in our samples.
