Specific heat measurements down to 80 mK in magnetic fields up to 8 T have been done on Sm3Se4 to check the heavy-fermion character in non-metallic materials. Heavy-fermion character with a large γ-value, 0.79 J/K2 mol Sm3+, is observed. Low-field magnetization measurements show magnetic ordering, presumably of frustrated kind, due to competing exchange interactions. Both the exchange mechanism and the possible Kondo state are discussed.
