## Description

- description: We show the giant magnetocaloric effect of HoNi2 compound can be tuned
    around hydrogen liquefaction temperature by substituting Ho with Gd and Ni with
    Co in Ho1-xGdxNi2-yCoy. While the Curie temperature of Ho1-xGdxNi2-yCoy can be
    tuned from 15 to 32 K originating from the lattice expansion of the cubic structure,
    giant entropy change of 22.0 J/kgK is retained near the hydrogen liquefaction
    temperature. A table-like entropy change observed in a broad temperature range
    of 20 to 32 K makes them promising as magnetocaloric materials for cryogenic magnetic
    refrigeration utilizing an Ericsson cycle.
