Abstract

Magnetic properties and magnetocaloric effects (MCEs) of the Dy ₃Co compound are studied. Two successive magnetic transitions: the antiferromagnetic (AFM)-to-AFM transition at T_AF = 29 K and the AFM-to-paramagnetic (PM) transition with increasing temperature at the Néel temperature T_N = 44 K are observed. Dy₃Co undergoes a field-induced metamagnetic transition from the AFM to the ferromagnetic (FM) state below T_N, giving rise to a large MCE. The maximal value of magnetic entropy change ΔSm is -13.9 J/kgK with a refrigerant capacity (RC) of 498 J/kg around T_N for a field change of 0-5 T. A sign change of MCE in Dy₃Co with magnetic field and temperature is observed near the critical field where the metamagnetic transition occurs.
