摘要：
Y2Fe17-xSix compounds with x = 0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 were investigated by magnetic measurement and NMR. It is found that with increasing Si content the Curie temperature T(C) increases while the average Fe magnetic moment mu(Fe) decreases. NMR study indicates that Si preferentially substitute the Fe atoms at 4f sites, which is responsible for the increase of T(C).
