摘要：
In this work, we investigate the magnetic properties of the V/W system, in the (001), (011), and (111) crystallographic orientations with and without relaxation at T = 0 K. Calculations of the magnetic moments are carried out using the real-space tight-binding method with a Hubbard Hamiltonian within the Hartree-Fock approximation. The coordination number, the type of the neighboring atoms, and the change of the vertical and horizontal distances between V atoms in the considered system are found to play a role in determining its magnetic properties. The magnetization is found to decrease when V is allowed to relax. The W interfacial layers acquired a sizeable induced magnetic moment. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
