Abstract
Spin polarization is investigated for Cr/Mn systems at T = 0 K using real-space tight-binding approach. The magnetism is described in the Hartree-Fock approximation of Hubbard Hamiltonian and the local density of states is calculated within the recursion technique. The magnetic moments for bulk Cr, and Cr-n/Mn interfaces for n = 1-3 overlayers with and without relaxation for low index crystallographic orientations are calculated. The antiferromagnetic ground state is considered for Mn (Cr) structures. The magnetism is most favored in the (111) orientation, whereas it has the least value in (011) orientation in all systems due to the coordination.
