Step Current Electrodeposition of nanocrystalline Ni 80Fe 20/Cu composite wires

Abstract

A new method called Step Current Electrodeposition (SCE) is proposed for the nanocrystalline deposition of high uniformity large coating thickness of Ni 80Fe 20/Cu composite wires. The hysteresis loops of the composite wires, developed by SCE and conventional plating, were measured using an inductance method and a magneto-impedance (MI) experimental setup, and the magnetic properties of the composite wires in terms of the hysteresis loops and the magneto-impedance effect were measured. The results showed that the experimental results obtained, which was in the trend of increasing GMI with increasing coating thickness till an optimum, agree well with the simulated results as found in the literature. 1 © World Scientific Publishing Company.
