Opis:: This paper presents the investigations of electrical properties and effect of annealing on conductivity of $(CoFeZr)_{x}(CaF_2)_{100-x}$ nanocomposites produced by ion-beam sputtering in the Ar and $O_2$ ambient. Investigations into conductivity of $(CoFeZr)_{x}(CaF_2)_{100-x}$ nanocomposites depending on the measuring temperature and the annealing temperature have been performed. The application of a combined argon-oxygen beam brings about lowering of the potential barrier on the surface of nanoparticles. In the course of annealing the additional oxidation occurs. First it proceeds on the surface and then all through the metallic-phase particles.

Opis:: In this paper the results of investigations of electrical properties of metal-dielectric nanocomposites $(FeCoZr)_x(CaF_2)_{100-x}$ are presented. The samples with the metallic phase content x=45.7 at.% were produced by ion-beam sputtering method in pure argon atmosphere, and subsequently annealed at 398 K for 15 min. The measurements of electrical properties were performed in the frequency range from 50 Hz to 1 MHz. The frequency dependences of phase angle θ, capacity $C_{p}$, conductivity σ and dielectric loss factor tanδ were measured at seven different temperatures ranging from 148 K to 263 K. It was found that the nanocomposite exhibits the phenomena of voltage resonance and current resonance, characteristic of the conventional RLC circuits with series and parallel connections of elements.
