摘要：

Specific heat measurements were carried out down to 80 mK in magnetic fields up to 8 T on Sm3Te4. Two sharp antiferromagnetic phase transitions were observed at 0.7 and 0.9 K. At 1.4 K, the specific heat shows a broad peak which can be fitted by the impurity Kondo model for S = 1/2. Heavy-fermion character at low temperature was established with a large gamma-value, 0.6 J/K2 mol Sm3+.
