Abstract

The specific heat of Sm₃Se₄ was measured between 0.15 and 5 K; it has a broad maximum around 1.2 K and a linear temperature dependence at around the lowest temperature. A γ-value of 4.5 J/molK² was obtained from this linear part. There are then low lying energy excitations with extremely large density of state in this compound and suggesting the possibility of a heavy fermion state with no free carrier. We checked this point by the measurements of magnetic susceptibility, specific heat and Mössbauer effect in a magnetic field to distinguish the possibility of a spin glass state.
