Abstract

Specific heat of ErCo₂ was measured in the temperature range 13 to 300 K. A sharp peak was observed at 32 K associated with a first order phase transition. The crystal field contribution to the specific heat was evaluated and crystal parameters were determined in both ferrimagnetic and paramagnetic regions. The saturation value of the magnetic entropy is quite close to R ln(2J + 1) = 23.1 (J/K mol), indicating negligibly small contribution of the Co moment. An entropy discontinuity at T_c can be understood by a sudden change of the ground state degeneracy.
