| Abstract: | The temperature and frequency dependences of the admittance real part in granular (Fe45Co45Zr10)x(Al2O3)100-x nanocomposite films around the percolation threshold xC were investigated. The behaviour of admittance real part 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 xC and of a metallic one beyond the xC determined as 54 +- 2 at.%. The mean hopping range d for the nanoparticles diameter D was estimated at different metallic phase content x. |
