Abstract

In film nanostructures based on cobalt and buffer layers of chromium group metals formed by magnetron sputtering, features of the conductivity of buffer layers of various thicknesses and the magneto-optical response of cobalt films on tungsten were revealed. Analysis of electron microscopy data, X-ray phase analysis, and magneto-optical measurements indicates the specific structure and properties of tungsten films, the resistance of which depends on their thickness and is determined by the charge transfer between the crystallites. There is no magnetic anisotropy in nanostructures based on tungsten/cobalt layers.
