Outstanding Magneto-Caloric Effect of a Gd$_{60}$Ni$_{37}$Co$_{3}$ Amorphous Alloy
2016
Outstanding magneto-caloric properties of a Gd60 Ni37Co3 amorphous alloy are reported. The magnetic entropy-change peak (−ΔSpeakm) near the Curie temperature (Tc = 135 K) of the amorphous alloy under 5 T is about 10.42 Jkg−1K−1 and the refrigeration capacity (RC) under 5 T is about 860 Jkg−1, both of which are almost the highest among the amorphous alloys with Tc above 100 K. The magneto-caloric behaviors and the mechanism for the rather high magneto-caloric effect of the Gd60Ni37Co3 metallic glass are investigated.
