Large adiabatic temperature rise above the water ice point of a minor Fe substituted Gd50Co50 amorphous alloy

Abstract
Abstract In this study, we have successfully improved the Curie temperature of Gd 50 Co 50 amorphous alloy from 267 K to 277 K by a minor Fe addition as a replacement for Co. The Gd 50 Co 48 Fe 2 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 (Δ T ad ) of the Gd 50 Co 48 Fe 2 amorphous alloy is comparable to that of the Gd 50 Co 50 amorphous alloy, both of which are larger than those of other metallic glasses near the ice point of water. The maximum Δ T ad of the Gd 50 Co 48 Fe 2 amorphous ribbon at 277.5 K is about 1.44 K under 1 T, 2.44 K under 2 T, 3.31 K under 3 T, 4.1 K under 4 T and about 4.84 K under 5 T. The large maximum value of Δ T ad above the ice point indicates that the Gd 50 Co 48 Fe 2 amorphous alloy could be an ideal candidate for the high efficient magnetic refrigerant in a household refrigerator.
