The temperature and frequency dependences of the admittance real part σ (T, f) in granular (Fe_{45}Co_{45}Zr_{10})_{x}(Al_2O_3)_{100 - x} nanocomposite films around the percolation threshold x_{C} were investigated. The behaviour of σ (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.
