چکیده انگلیسی
The magnetic properties and magnetic entropy change of amorphousized Tm60Co20Ni20 ribbon were systematically studied. The results indicate that the Tm60Co20Ni20 amorphous ribbon reveals a second order magnetic transition (paramagnetic to ferromagnetic state) based on the Arrott plots and rescaled magnetic entropy change curves. A large magnetic entropy change is achieved around its Curie temperature of TC â¼6.7 K. Under the magnetic field change (ÎÎ) of 0-5 T, the maximum values of magnetic entropy change (âÎSMmax) and relative cooling power (RCP) are 17.1 J/kg K and 273 J/kg, respectively. In particular, under a relative low ÎÎ of 0-2 T, a large magnetic entropy change of 11.8 J/kg K reaches, making it attractive in the field of low-temperature magnetic refrigeration.
