Abstract
The influence of deposition parameters on the structure and magnetic properties of CoP/Cu composite wires had been studied systematically in this paper. These parameters hold a significant effect on the surface topography, coating composition, deposition rate, magnetic properties and giant magnetoimpedance (GMI) effect of the composite wires. The CoP/Cu composite wire is layered clearly, the coating is uniform and the soft magnetic properties is excellent, the largest value of field sensitivity (ξ) is 195%/Oe and the maximum GMI ratio is 902%, which is the highest GMI value of the CoP composites materials so far. This result will be great significance for further study of the application of magnetic sensors.
