Low field induced large magnetic entropy change in the amorphousized Tm60Co20Ni20 ribbon
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 ∼6.7 K. Under the magnetic field change (ΔΗ) of 0-5 T, the maximum values of magnetic entropy change (−ΔSMmax) and relative cooling power (RCP) are 17.1 J/kg K and 273 J/kg, respectively. In particular, under a relative low ΔΗ 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.
