Abstract

Herein, we report high magnetocaloric performance of melt-extracted metallic glass Gd₆₀Al₂₀Co₂₀ microwires, which exhibit a large and reversible magnetocaloric effect (MCE). The isothermal magnetic entropy change (-ΔS_m) reaches as high as 10.1 J kg^-1 K^-1 and the refrigerant capacity (RC) has a large value of 681 J kg^-1 for a field change of 5 T. The as-obtained Gd-based metallic glass microwires hold a great promise for multifunctional applications in MCE-based refrigeration of liquid nitrogen temperature range.
