用真空高频磁悬浮炉制备了Gd0 9Zn0 1,Gd0 8Zn0 2 ,Gd0 7Zn0 3 3种合金 ,并用直接测量法测量了样品及纯Gd在 1 5T磁场下的磁热效应 ,发现Gd1-xZnx(x=0 .1,0 .2 ,0 .3)系合金仍具有较大的磁热效应 ,且其最大绝热温变ΔTad 随x的增加而降低 ,是一种可供选择的室温磁制冷材料 Gd0 9Zn0 1, Gd0 8Zn0 2, Gd0 7Zn0 3 3 alloys were prepared by vacuum high-frequency magnesia furnace. The magnetocaloric effect of Gd1-xZnx1 (x = 0 .1,0 .2, 0 .3) alloys still have a larger magnetocaloric effect, and the maximum adiabatic temperature change ΔTad decreases with the increase of x, which is an alternative room temperature magnetic refrigeration material
