英文摘要	The Gd25Co25Al25Ho25-xYx (x = 1, 5, 10, and 15) high entropy metallic glasses are fabricated by copper-mold quenching technique. Substituting moderately Ho with Y effectively improves the glass-forming ability, magnetic entropy change (vertical bar Delta SM vertical bar), and magnetic refrigeration capacity (RC) of Gd25Co25Al25Ho25-xYx. Besides, the Curie temperature of this quaternary alloy can be tuned from 51 to 41 K with Y addition. Among these alloys, Gd25Co25Al25Ho20Y5 exhibits the largest peak value of vertical bar Delta SM vertical bar up to 8.79 J kg(-1)K(-1) and the corresponding RC up to 547 J kg(-1) under a magnetic field of 5 T. It is worthy to note that a reverse changing trend can be observed between the maximum vertical bar Delta SM vertical bar and the temperature range of magnetic transition, which may be ascribed to the spatial inhomogeneity induced by yttrium microalloying. Our studies show that yttrium is an effective element to manipulate magnetocaloric properties of high entropy metallic glasses as potential refrigerants.
