【 摘 要 】

A sensor for studying nanomaterials has been developed on the basis of a transformer-type eddy-current transducer. The basic technical data are stated (the number of windings is 100-400 turns, and the value of the initial permeability of the core is μmax= 36000). Measurements technique which allows high-precision measuring the electrical conductivity in thin film Ce-Nb. The electrical conductivity of Niobium-Selenium varies from 3.3•105to 3.7•105MS/m in the ratio of four from 4 to 60 nm.
