Abstract

A new heavy rare-earth-based Ho₃₆Dy₂₀Al₂₄Co₂₀ bulk metallic glass (BMG) has been prepared by a copper mold casting. A maximum magnetic entropy change of 11.77 J/kg K has been measured in Ho₃₆Dy₂₀Al₂₄Co₂₀ bulk metallic glass under a magnetic field of 5 Tesla, which is larger than that of the early reported Ho-based bulk metallic glass Ho₃₀Y ₂₆Al₂₄Co₂₀. The half-maximum temperature range of the entropy change peak is as large as 40 K, leading to a superior refrigerant capacity to those of the Gd₅Si₂Ge₂ and Gd₅Si₂Ge_1.9Fe_0.1 crystalline compounds. The excellent magnetocaloric effect together with the unique properties of metallic glass makes this alloy a promising candidate for a magnetic refrigerant in the temperature range below 50 K.
