Abstract

We report the magnetic and magnetocaloric properties of HoCoSi, which shows second order ferro-paramagnetic transition at 14 K. It is found to exhibit a large magnetic entropy change of 13 J/kg K for a field change of 20 kOe, which increases to 20.5 J/kg K at 50 kOe. The refrigerant capacity is found to be 135 and 410 J/kg for 20 and 50 kOe, respectively. The large- and low-field adiabatic temperature change (~3 K) and the large refrigerant capacity make this compound a suitable candidate for magnetic refrigeration applications at around 15 K.
