摘要:
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 T-C similar to 6.7 K. Under the magnetic field change (Delta H) of 0-5 T, the maximum values o ...More
