Fe-KCl石墨层间化合物磁学性能研究

STUDY ON THE MAGNETIC PROPERTIES OF COMPOUND IN THE INTERCALATION OF Fe-KCl GRAPHITE

探讨了Ｆｅ－ＫＣｌ石墨层间化合物的某些磁学性能．在宏观上，它能被永久性磁铁吸引，表现出明显的单轴磁各向异性，磁化方向仅为平行于碳网面的一个固定方向．当外磁场撤消，剩磁随之消失．在微观上通过插入物粒度测量及Ｍｓｂａｕｅｒ谱研究证实它有典型的超顺磁性．

Some magnetic properties of compound in the intercalation of Fe-KCl graphite are studied. Macroscopically the compound can be attracted by magnet, and shows the single_axis magnetic anisotropy obviously and the magnetized direction is the only fixed one that parallel to the carbon net surface. With the outer magnetic field withdrawn, the residue magnetism disappears. Microscopically it is testified by intercalated particle size test and Mssbauer spectra that the compound has typical super_paramagnetic property.
