	The temperature and frequency dependences of the admittance real part sigma(T, f) in granular (Fe45Co45Zr10)(x)(Al2O3)(100-x), nanocomposite films around the percolation threshold x(C) were investigated. The behaviour of sigma(T, f) vs. the temperature and frequency over the ranges 77-300 K and 50 Hz-1 MHz, respectively, displays the predominance of an activation (hopping) conductance mechanism for the samples below the percolation threshold x(C) and of a metallic one beyond the x(C) determined as 54 +/- 2 at.%. The mean hopping range d for the nanoparticles diameter D was estimated at different metallic phase content x.
