Magneto-Impedance Tomography of Composite CuBe/FeCoNi Wires

Abstract

The results of investigation of the distribution of electrical and magnetic properties over the cross-section are presented for Cu[Formula: see text]Be2/Fe[Formula: see text]Co6Ni[Formula: see text] composite wire of the “highly conductive core-magnetically soft coating” type, obtained by electrolytic deposition of the FeCoNi layer. Studies performed by the magneto-impedance tomography (MIT) made it possible to determine the specific electrical conductivity of the materials of the core and coating. It was established that the electrodeposited coating had a magnetic structure that was inhomogeneous over the thickness.
