Аннотация Present results of studies of the phase composition, microstructure and magnetoresistive properties of three-layer film Fe / Pt / Fe (total concentration of platinum atoms сPt ≤ 20 аt. %) and multilayers based on Fe and Pt (20 ≤ сPt ≤ 33 аt. %), where possible formation diluted s.s. of Pt atoms in α-Fe layers and phase Fe3Pt based on Pt island, in non-annealed and annealed to 800 K states. Analysis of the results combined with literature data suggests that the phase composition of the magnetic grains did not significantly affect the efficiency of spin-dependent electron scattering.
