Abstract

In this paper we present an approach of the obtaining and study of nanostructured materials with special resistive magnetic properties. The Cu and Co thin films are grown by a physical thermionic vacuum arc method (TVA). Successive layers of Cu and Co were deposited on ceramic substrates using tungsten crucibles each containing Cu and Co metals, respectively. The morphological and structural investigations were achieved by means of electron microscopy technique: TEM (Philips, CM120ST). The compositional analysis of the films was performed by an X-ray spectroscopy and correlated to the electrical resistance..
