The study of the structure, phase composition and electrical conductivity of FexCo1 – x (x ≅ 0.2) thin films and three-layer systems on their basis with a copper layer was conducted. It is shown that the phase composition of as-condensed films corresponds to BCC FeхСо1 – x + HCP-Co, and after annealing at 700 K is fixed only BCC FeхСо1 – x. In FeхСо1 – x/Cu/FeхСо1 – x films with dF = 20-40 nm and dN = 5-20 nm, the phase composition corresponds to the eutectic of the BCC-FeхСо1 – x + FCC s.s Cu (Fe or Co), regardless of the heat treatment conditions. On the temperature dependence of the resistivity identified and justified three typical areas
