摘      要：A Magneto-impedance (MI) effect has been investigated in electrodeposited wires composed of non-magnetic conductive core coated by a soft ferromagnetic layer. In this work, a 460 µm Cu wire is coated with three soft ferromagnetic layers of Ni80Fe20 sandwiched by a thin Cu layer. The MI effect has been measured as a function of the sample length in low frequency (20 kHz – 100 kHz). The MI ratio raises by increasing the wire length; it increases approximately 400% by the increases the length of wire from 1 cm to 4 cm. This work also shows a significant increase in the field sensitivity by increasing the wire length significantly.
