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．
The metal Fe nanocrystalline powders were prepared by ball milling in different atmospheres. The structure changes of the samples before and after the ball milling were analyzed by X-ray diffraction. The structure of the nanocrystals was studied by Mssbauer spectrum. The results show that different atmospheres significantly affect the electronic structure and magnetic structure of the nanocrystalline interface.
