Abstract
The magnetocaloric effect (MCE) of quaternary intermetallic compound ErNiBC has been investigated by magnetization and heat capacity measurements. The compound undergoes a paramagnetic (PM) to ferromagnetic (FM) transition at TC~5 K and the ground state of Er ion forms a Kramer's doublet state. The magnetic transition is found to be second order in nature. The maximum magnetic entropy change (−ΔSMmax) and adiabatic temperature change (ΔTadmax) of ErNiBC are 24.8 J/kg K and 8.6 K, respectively, for a magnetic field change of 0–50 kOe, and the corresponding refrigerant capacity (RC) is 312 J/kg.
