摘要
在不同气氛下应用球磨法制备了金属Ｆｅ纳米晶粉末，用Ｘ射线衍射分析球磨前后样品的结构变化，Ｍｓｓｂａｕｅｒ谱研究了纳米晶的结构特牲．结果表明，不同气氛显著影响纳米晶界面组元的电子结构和磁性结构．
Nanocrystalline metallic iron powder was prepared under either Ar or N2 atmosphere by a vibratory ball mill. The X-ray diffractions (XRD) were used to monitor the structure changes during ball milling. Nanostructure of metallic Fe was further studied by Mssbauer effect. The structure of the electron and magnetism of the interface component in Fe nanocrystals was abviously effected by the milling atmosphere.
