Annealing of (CoFeZr)x(CaF2)100-x nanocomposites produced by the ion-beam sputtering in the ar and O2 ambient

Abstract

This paper presents the investigations of electrical properties and effect of annealing on conductivity of (CoFeZr)x(CaF2) 100-x nanocomposites produced by ion-beam sputtering in the Ar and O2 ambient. Investigations into conductivity of (CoFeZr) x(CaF2)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.
