Abstract: NiFe/Au composite wires were deposited by electrodeposition. Current annealing and temperature effect on the properties of NiFe/Au composite wires were investigated in detail. The results indicate that the introduced stress inside the deposited layer leads to increased coercivity and decreased Giant Magneto-Impedance (GMI) effect. Ni80Fe20/Cu composite wire deposited under an optimised condition shows a sensitivity of 4.64 mV/μT when the wires were made as sensing elements of an orthogonal fluxgate sensor. In addition, the work also shows that saccharine and boric acid play important roles for properties of the deposited wires.
