Excellent magneto-caloric effect of a binary Gd63Ni37 amorphous alloy

摘要

In the present work, we reported an excellent magneto-caloric effect (MCE) of a binary Gd63Ni37 amorphous alloy. The amorphous features of the Gd63Ni37 as-spun ribbons were ascertained by their Xray diffraction pattern, differential scanning calorimetry (DSC) curve and their magneto-caloric behaviors. The Gd63Ni37 amorphous ribbon exhibits rather high magnetic entropy change peak (-Delta S-m(peak)), refrigeration capacity (RC) and adiabatic temperature rise (Delta T-ad). The binary Gd63Ni37 amorphous alloy is expected to play an important role in developing high performance multi-component Gd-Ni-based amorphous magnetic refrigerants. (C) 2017 Elsevier Ltd.
