Annotation | The structural-phase composition and magnetoresistive properties of as-deposited and annealed at 400, 550 and 700 K temperatures of the layered film systems based on ferromagnetic alloy (FexNi100 – x) (F – layers) and Cu (N – layer) obtained layer by layer condensation method were investigated. A phase state of the film samples (dF = 10-50 nm and dN = 5-20 nm, х = 20-40 %) is fcc-Ni3Fe (а = 0,355-0,358 nm) and fcc-Cu phases. The samples with Ni concentration in magnetic layers х = 50-60 % have a two-phase structure – fcc-NiFe (а = 0,358-0,362 nm) + fcc-Cu. After annealing at 700 K in these systems are formed solid solutions (Ni3Fe, Cu) and (NiFe, Cu), respectively. For the as-deposited and annealed at 700 K samples with х > 60 % the phase state is bcc-(Fe-Ni) + fcc-Cu. In the thickness layers range dN = 5-15 nm and dF = 25-40 nm (cNi = 90 %) for three-layers samples realized spin-dependent scattering of electrons was shown. |
