| 摘 要： | 研究了Fe-Ga合金中Ga原子对合金的平均原子磁矩的影响.Fe中掺入Ga原子后,并不是简单的"稀释"作用.与纯Fe的原子磁矩相比,Fe-Ga合金中平均原子磁矩减小的同时,在低Ga含量范围,Fe原子的磁矩随Ga含量的增加而增大;当Ga含量大于17%(原子分数)时,Fe原子磁矩随着Ga含量的增大而减小.

| Abstract: | The effect of Ga atom on the mean magnetic moment per atom of Fe-Ga alloys was discussed. It was found that Fe-Ga alloys exhibit a markedly different behavior from simple magnetic dilution. With the decrease in mean moment per atom, the moment-per-iron atom increases with the substitution of Ga atom and decreases when the content of Ga atom is larger than 17%. |
