C(2X2) AND P(1X1) MAGNETIC ORDER OF CR PD(001)/

We have investigated the magnetic order of the Cr/Pd(001) interface sy stem using a self-consistent tight-binding model in a mean-field appro ximation. The method is formulated in terms of localized orbitals. The recursion method is used to calculate the densities of states. Thick Cr layers up to eight atomic layers are investigated. A p(1 x 1) layer ed antiferromagnetic structure (LAF) and a c(2 x 2) in-plane antiferro magnetic structure (IAF) in the Cr layers are considered. (C) 1998 Els evier Science B.V. All rights reserved.
