The magnetic and magnetocaloric properties of the intermetallic compound ErRuSi have been investigated. The compound shows ferromagnetic ordering with Curie temperature of 8 K. The magnetic transition is found to be first order in nature. The maximum entropy change and refrigerant capacity are found to be 21.2 J/kg K and 416 J/kg for a field change of 50 kOe. The low field (20 kOe) entropy change is also found to be quite large (15.2 J/kg K). Additionally, the compound shows very little thermal and field hysteresis, fulfilling the required condition for a good magnetic refrigerant in the low temperature regime.
