چکیده انگلیسی
For the potential applications in magnetic refrigeration, low-cost and high-performance refrigerants with large magnetocaloric effect at relatively lower field change are highly desired. In this work, we report a large adiabatic temperature variation for a low-field change of 1.5â¯T near room temperature in a Ni40Co8Mn42Sn10 bulk alloy. With the large magnetization difference between weak magnetic martensite and ferromagnetic austenite, this alloy exhibits significant inverse magnetocaloric effect. Under the field change of 5â¯T, large magnetic entropy change ÎSM of 21.6â¯Jâ¯kgâ1Kâ1 and effective refrigeration capacity RCeff of 293â¯Jâ¯kgâ1 were achieved. Moreover, a large ÎTad up to â4.4â¯K was obtained under the low-field change of 1.5â¯T, which is much higher than previously reported ÎTad values in Ni-Mn-Sn based alloys.
