	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.
