Abstract
In the present work, we studied the microstructure, thermal and magnetic properties of a Gd48Co50Nb2 amorphous ribbon for the purpose of revealing the mechanism of the table-like magnetic entropy change (âÎSm) profile of the ribbon. It was found that the amorphous ribbon was fully amorphous with only short-range orders. The two-step magnetic phase transitions indicate that there are two amorphous phases in the Gd48Co50Nb2 amorphous ribbon. The table-like âÎSm profile of the Gd48Co50Nb2 amorphous ribbon is supposed to be due to the superposition of two âÎSm peaks corresponding to two separated amorphous phases with different magnetic properties. The amorphous ribbon is expected to be a good candidate for magnetic refrigerant because of its high maximum âÎSm and high effective refrigeration capacity of the specific table-like âÎSm profile.
