Abstract

The magnetic properties and magnetocaloric effects (MCEs) have been investigated in ErSi compound, which crystallizes in the orthorhombic CrB-type structure. This compound is antiferromagnetic (AFM) with a Néel temperature T_N of 12.5 K. The measurements of the temperature and field dependences of the magnetization clearly show that the ErSi compound undergoes a field-induced metamagnetic transition from AFM to ferromagnetic (FM) state below T_N. The isothermal magnetic entropy change (Δ S_M) and refrigerant capacity (RC) of ErSi have been measured for various applied magnetic fields and their values are found to be -14.8J·kg^-1·K^-1 and 210 J·kg ^-1 for a field change of 0-5 T, respectively. The large MCE is attributed to the field-induced AFM to FM metamagnetism occurring in this compound.
