The results of the investigations of the polarization properties in thin layers of vitreous Ge_28.5Pb_14.0Fe_1.0S_56.5 are presented. A process of dipole-relaxation polarization was discovered, the activation energy of which turned out to be equal to E_a=(0.97±0.14) eV. It has been determined that charge transfer in the Ge_28.5Pb_14.0Fe_1.0S_56.5 hybrid system is a thermally activated process with an activation energy of E_a=(0.54±0.01) eV. The calculation results allow us to conclude that the glass-forming capacity of the (Ge_28.5Pb_15.0S_56.5)_100-xFe_x system decreases linearly with an increase in the proportion of metal in the glass structure. Keywords: charge carrier hopping, thin layers, hybrid chalcogenide, lone-pair electrons.
