The study of carrier transport in granular nanocomposite films consisting of ferromagnetic Fe45Co45Zr10 alloy nanoparticles embedded in a low-conductive Pb81Sr4(Na5Bi5)15(Zr57:5Ti42:5)O3 matrix has been performed. Real part of the impedance of the nanocomposites was studied as a function of composition, temperature and frequency, for the samples with 25 - x - 80 at.%, deposited by ion-beam sputtering in Ar + O2 gas mixture at the oxygen pressures of PO2 = 2:4 -10-3-and-3:7---10-3-Pa.-It-has-been-proved-that-approaching-the-threshold-concentration,-xC-in-the-FeCoZr-alloy-resulted-in-the-transition-from-high-ohmic-to-low-ohmic-state-with-the-x-increase,-without-the-change-of-hopping-mechanism-of-carrier-transport.
