Abstract
The magnetic structure of Cr/V systems is investigated at TÂ =Â 0Â K using real-space tight-binding approach. The magnetism is described in the Hartree-Fock approximation of the Hubbard Hamiltonian and the density of states is calculated within the recursion technique. It is found that the hybridization of the V and Cr d-bands, the change in the lattice constant, the kind and the number of coordination play important roles in determining the magnetism of Cr and V atoms.It is also found, that the magnetic moments of Cr, and the induced magnetic moments on V atoms have the maximum value at (0Â 0Â 1) orientation, followed by (1Â 1Â 1) orientation, and the least at (0Â 1Â 1) orientation, due to the coordination.
