The calculation of magnetoresistance coefficient for multilayer magnetic structures

We performed a simulations of magnetic properties for the multilayer structures Fe/Cr/Fe and Co/Cu/Co using the Monte Carlo methods and the anisotropic Heisenberg model. The calculation of magnetoresistance coefficient is implemented in case of CPP geometry for the different thicknesses of the ferromagnetic films. The calculated dependence of the magnetoresistance coefficient on temperature is agreed very well to the experimental data. The values of the thickness of the ferromagnetic film corresponding to the highest value of magnetoresistance coefficient were determined.
