چکیده انگلیسی
The magnetic structure of V/Mn systems is investigated at T=0Â K using real-space tight-binding approach. The magnetism is described in the Hartree-Fock approximation (HFA) of the Hubbard Hamiltonian and the density of states is calculated within the recursion technique. The semiempirical tight-binding (TB) method is used to investigate the magnetism of the systems, where the Hamiltonian is constructed using the Slater-Koster (SK) parameters. It is found that the hybridization of V with Mn d-bands and the neighboring effects play decisive roles in determining the magnetic structure of V-Mn systems. It is found that the magnetic moments of V and Mn in the (111) orientation are greater than those of (001) orientation for one and two V overlayers due to the local environment.
