Abstract

Monte Carlo simulations of magnetic properties for structures, which are constructed from two ferro- magnetic films divided by nonmagnetic film, are carried out using the anisotropic Heisenberg model. The value for exchange integral for Fe(100)/Cr system was calculated using PAW PBE approximation. The calculation of the magnetoresistance coefficient is carried out for different thicknesses of the ferromag- netic films in case of CPP geometry. It was shown, that the obtained temperature dependence for the magnetoresistance coefficient is agreed very well with experimental results, measured for the Fe/Cr and Co/Cu multilayered structures
