Investigation reveals a 16.65 J/(kg × K) peak magnetic entropy change in the Er69Ni31 amorphous alloy, suggesting notable magnetocaloric performance.
The magnetocaloric response of an amorphous Er69Ni31 alloy was studied in the present work. The eutectic Er69Ni31 alloy was successfully melt-spun into an amorphous ribbon. The formability and magnetocaloric performance of the Er69Ni31 amorphous alloy were studied. The amorphous sample exhibits good glass formability and a remarkable magnetocaloric effect with a magnetic entropy change peak of ~16.65 J/(kg × K) near 10 K under 5 Tesla. The magnetization and magnetocaloric behaviors were investigated to reveal the effect of spin-glass-like behaviors on the magnetocaloric response of the binary amorphous sample.
