摘　　要：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 。Gd0.9Zn0.1,Gd0.8Zn0.2,Gd0.7,Zn0.3 alloys were prepared in a high-frequency floating furnace. The magnetocalorie effect of Gd0.9Zn0.1,Gd0.8Zn0.2,Gd0.7,Zn0.3 alloys and pure Gd were measured directly at the magnetic field of 1.5 Tesla. It is found that the Gd1-xZnx（x = 0.1, 0.2,0.3） have large magnetocaloric effects, and the largest △Tad decreases gradually with increasing x for Gd1-xZnx system alloys near room temperature.
