摘要: The magnetization distribution, its energetic characterization by the interlayer coupling constants and lattice dynamics of (001)-oriented Fe/Pt multilayers are investigated using density functional theory combined with direct method to determine phonon frequencies. It is found that ferromagnetic order between consecutive Fe layers favoured, enhanced magnetic moments at interface. bilinear biquadratic coefficients shown saturate fast increasing thickness nonmagnetic Pt which separate them. calculations demonstrate a rather strong dependence partial iron densities states on actual position monolayer in multilayer structure.
