ملخص: We have investigated the magnetic behavior of strained bcc Fe epitaxied on semi-infinite Ir(001) by using tight-binding Hamiltonian in the unrestricted HFA including s, p and d electrons. The Fe interlayer coupling is found to be antiferromagnetic (AF) for all the five systems, Fex/Ir (001) x=1-5 ad-layers. The sub-interface plane of Ir is not affected by the deposited magnetic films. The absolute value of the magnetic moment of the Fe layer at the interface decreases with the increase of the Fe thickness. The surface layer presents the largest magnetic moments. For all Fe on Ir (001) systems, the magnetic moment of Fe planes remains smaller than the bulk value.
