Abstract The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh symmetry have been studied by MS-Xα method. The results show that (1) The exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters; (2) The charge distribution in both clusters is not uniform, showing that the electrons are transferred from peripheral atoms to inner atoms, and the spin-direction (up or down) of the electrons transferred is in accordance with the symmetric characteristics of the clusters.
