The magnetic susceptibility of Bridgman-grown Sn1-xEuxTe with nominal values of x up to 0.095 was measured over a temperature range from 2 to 385 K. The samples were p-type with hole concentrations up to 1.5x 1021 cm-3 . The susceptibility data above 50 K followed the Curie-Weiss relation with a small Curle temperature. At about 10 K a small cusp in susceptibility was observed in samples with the higher range of x values. The data indicate á presence of both antiferromagnetic and ferromagnetic
