Description Large magnetocaloric effect (MCE) and magnetoresistance (MR) together with negligible hysteresis loss have been observed in ErNiSi compound, which undergoes metamagnetic transition at low temperatures. Magnetization, heat capacity, and resistivity measurements confirm the metamagnetic transition. Both MCE and MR follow H-2 dependence in the paramagnetic regime. The maximum value of isothermal entropy change (Delta S-M) and MR for a field change of 50 kOe are found to be 19.1 J/kg K and similar to 34%, respectively. Large MCE with negligible magnetic hysteresis loss could make this material promising for low temperature magnetic refrigeration. (C) 2014 AIP Publishing LLC.
