Abstract

Giant magneto-impedance (GMI) effects were investigated in CuBe/CoNiP and CuBe/Insulator/CoNiP composite wires prepared by electroless deposition on pure or insulated CuBe wires. Experimental results show that the maximal GMI ratio and the field sensitivity of the composite wires are further improved by adding an insulator layer between the CuBe core and ferromagnetic layer. A distinct MI effect was observed in the composite wires with insulator even at low frequencies. MI ratio is about 18% at 20 kHz and 239% at 600 kHz. The maximal field sensitivity is 34%/Oe at 600 kHz. The properties of GMI in these composite wires are analyzed via complex permeability.
