%J 中国物理快报 %D 2009 %I %X The geometries and electronic properties of Fe(MgO)n are systematically investigated by the density functional theory. The results show that the doped Fe atom is prone to bond with the O atom, and Fe almost does not disturb the frame of (MgO)n. The second-order energy difference, the fragmentation energies and the electron affinities show that Fe(MgO)4 and Fe(MgO)6 possess relatively higher stabilities. The HOMO-LUMO gaps of Fe(MgO)n decrease obviously as compared with (MgO)n. Almost equal unpaired electrons of the 3d state of the Fe atom in Fe(MgO)n result in a nearly equal magnetic moment of Fe(MgO)n. %K 31 %K 15 %K A- %K 36 %K 40 %K Cg
