不同剂量的硼离子注入的多晶铁薄膜的磁导率随注入剂量增加呈现非单调上升,其57Fe转换电子穆斯堡尔谱显示了非晶态合金的生成,结果支持临界缺陷密度非晶化模型。The permeability of polycrystalline iron thin films implanted with different doses of boron ions rises nonmonotonously with increasing dose, while the 57Fe conversion electron Mossbauer spectra of the films have shown the formation of amorphous metallic alloy. The results favour the critical defect density model of amorphous state formation.
