We report the formation of a Gd10Tb10Dy10Ho10Er10Y10Ni10Co10Ag10Al10 denary high entropy metallic glass (HEMG). The magnetocaloric effect studies show that the denary HEMG possess large magnetic entropy changes over a wide temperature range, and thus a large refrigerant capacity. Combined with the simple alloy design of high entropy alloys and atomic level homogeneous single phase nature of metallic glasses, the magnetocaloric properties of HEMGs can be easily adjusted by changing the elements or configurational entropy. Our works show that the HEMG is a promising candidate material as the magnetic refrigerant. (C) 2018 Elsevier B.V. All rights reserved.
