摘要：

In the present work, we reported an outstanding magneto-caloric effect near room temperature of a binary Gd48Co52 amorphous alloy. Both the magnetic entropy change peak and refrigeration capacity of the Gd48Co52 amorphous ribbon are higher than most of the values of other amorphous alloys near room temperature. The maximum adiabatic temperature rise near room temperature of the Gd(48)Co(52 a)morphous ribbon is comparable to or even larger than those of other Gd-based metallic glass at low temperature. The binary Gd48Co52 amorphous alloy is expected to play an important role in developing high performance multi-component amorphous refrigerants near room temperature. (C) 2015 Elsevier B.V.
