Annotation It was stated that during oriented film system growth on MgO(100) crystal the significant magnetic anisotropy is observed. It appears in increase of coercive force (BC) in two times and significant variation of magneto resistance at different turn angles. AFM investigations showed that surface roughness of Au(2 nm)/Co(30 nm)/Fe(30 nm)/MgO filem system in four times lower than of sample on amorphous substrate (non-annealed). Besides the diffusion processes in systems that were built on MgO monocrystall proceed less intensive than in case of SiO2/Si.
