Excellent magneto-caloric effect of a binary Gd63Ni37 amorphous alloy

Abstract In the present work, we reported an excellent magneto-caloric effect (MCE) of a binary Gd 63 Ni 37 amorphous alloy. The amorphous features of the Gd 63 Ni 37 as-spun ribbons were ascertained by their X-ray diffraction pattern, differential scanning calorimetry (DSC) curve and their magneto-caloric behaviors. The Gd 63 Ni 37 amorphous ribbon exhibits rather high magnetic entropy change peak (−Δ S m peak ), refrigeration capacity ( RC ) and adiabatic temperature rise (Δ T ad ). The binary Gd 63 Ni 37 amorphous alloy is expected to play an important role in developing high performance multi-component Gd-Ni-based amorphous magnetic refrigerants.
