Abstract: In this study, we have successfully improved the Curie temperature of Gd50Co50 amorphous alloy from 267 K to 277 K by a minor Fe addition as a replacement for Co. The Gd50Co48Fe2 as-spun ribbons exhibit typical characteristics of a soft magnetic amorphous alloy. The magnetic entropy change peak for this amorphous alloy was slightly decreased by the minor Fe addition, but the adiabatic temperature rise (Delta T-ad) of the Gd50Co48Fe2 amorphous alloy is comparable to that of the Gd50Co50 amorphous alloy, both of which are larger than those of other metallic glasses near the ice point of water. The maximum Delta T-ad of the Gd50Ca48Fe2 amorphous ribbon at 277.5 K is about 1.44 K under 1 T, 2.44 K under 2 T, 331 K under 3 T, 4.1 K under 4 T and about 4.84 K under 5 T. The large maximum value of Delta T-ad above the ice point indicates that the Gd(50)Co(48)F(e)2 amorphous alloy could be an ideal candidate for the high efficient magnetic refrigerant in a household refrigerator.
