Zusammenfassung:
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
gamma-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.
