Abstract:
The magnetocaloric effect in Ni-Co-Mn-In alloys is studied at low magnetic field, across the first order magnetostructural transition. The Co doping at Ni site induces the large magnetic entropy change (Delta S-m) above room temperature. The large Delta S-m of 11 J/ Kg K has been observed for disordered Ni1.81Co(0).22Mn1.46In0.51 alloy at 337 K at an applied field of 1.5 Tesla. The influence of quench atomic disorder on the magnetocaloric properties of Ni-Co-Mn-In alloys has been studied. The atomic disorder significantly increases the peak value of DSm and decreases the peak width. The refrigeration capacity (RC) is almost unchanged with atomic disorder.
