Abstract
In the present work, the Curie temperature (Tc) of the Co50Gd48Fe2 amorphous alloy, which exhibits high adiabatic temperature change (ΔTad) at room temperature, was further improved by small amount of Ni substitution for Gd. The maximum magnetic entropy change (−ΔSmpeak) of the Co50Gd48-xFe2Nix (x = 1 and 2) amorphous ribbons decreases with Ni addition, but is still large than those of the Fe-based metallic glasses. The maximum ΔTad of the Co50Gd48-xFe2Nix glassy alloys near the hot end of a residential refrigerator, which is at least 65% higher than those of the Fe-based glassy ribbons, indicates that the Co50Gd48-xFe2Nix amorphous alloys are the better candidates for the domestic magnetic refrigerants.
