摘要：

Spin polarized total energy and electronic structure calculations are performed for thin Fe nanowires using the ab initio pseudopotential plane wave method within generalized gradient approximation. Binding energy, density of states, and magnetic moment are calculated for planar and staggered thin Fe wires, which are composed of four atoms or less. The most stable configuration is attained in zigzag geometry of which the bond length is stretched relatively to the planar nanowire. The Fe-zigzag wire has the largest magnetic moment among isomers. Upon stretching the Fe-2-zigzag wire to a linear one, the magnetic moment increased to be proportional to the nearest-neighbor distance. (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
