摘要：
The local magnetic moments of Fe-1 /V-N nanoinclusions in bulk Fe are determined by using a realistic spd-band Hubbard-like model. The spin density distribution is calculated self-consistenly in the unrestricted Hartree-Fock approximation. The local magnetic moments mu(i) are obtained at various atoms i of nanoinclusions and of the surrounding matrix. The Fe atoms couple always antiferromagnetically with the V atoms. In most cases the Fe moments close to the V atoms are reduced. A remarkable interplay between the paramagnetism of V and the ferromagnetism of Fe is obtained. (C) 2003 Published by Elsevier B.V.
