“…Commonly, the composite wires were fabricated by magnetron sputtering [11], electroplating [12][13][14][15][16], chemical plating [17], or MEMS technique [18]. However, the GMI sensitivity of the composite wires is not high since their magnetic structure cannot be well controlled by these methods.…”

Abstract:CuBe composite wires of 100 μm in diameter coated with a layer of NiCoP were prepared by a chemical plating method under DC current (CPUDC). The influences of DC current on coating morphology, deposition rate, composition, giant magneto-impedance (GMI) effect and magnetic properties were investigated. It was shown that the circumferential domain structure of coating layer was induced by the DC current going through the wires. A maximum GMI ratio of 870% was obtained in the composite wire prepared under 150 mA and tested at 180 kHz. It is 30 times higher than that of the composite wire plated in the same condition by conventional chemical plating method, indicating that CPUDC is an easy and effective approach to obtain composite wires and its applications will be further extended on magnetic sensors.

“…It is evident that the highest MI ratio was obtained when pH value is 8.4. The optimal pH value is much higher than that of electroplating method [13][14][15][16]22]. The pH value was kept at 8.4 in the following CPUDC method.…”

“…Electroplated wires are composite materials consisting of a conducting non-magnetic core and magnetically soft tube covering, which can be FeNi [4,10], FeCoNi [5,6], CoP [12,13], Co [14], NiFeMo [10], NiFeRu [15]. A wide variety of compositions of magnetic layer was investigated in order to obtain as high as possible values of the GMI variations and high values of sensitivity with respect to an external magnetic field.…”

Giant magnetoimpedance effect (GMI) is a subject of special interest proved by applied electrodynamic and technological applications. GMI effect in ferromagnetic tubes is connected with the high sensitivity of the magnetic system to a circular magnetic field near the spin-reorientation magnetic phase transitions offering high sensitivity with respect to an external magnetic field. In this work the non-magnetic CuBe wires were covered by Fe 20 Co 6 Ni 74 layers by electrodeposition. The thickness of 1 μm for magnetic layer was high enough in order to ensure the high GMI value. Longitudinal magnetic anisotropy was induced by post preparation annealing in a magnetic field of 160 A/m at 320˚C during 1 hour in order to obtain appropriate magnetisation process. Angular dependencies of GMI were measured in a frequency range of 1 to 10 MHz for driving currents of 2.5 to 20 mA. High longitudinal GMI of the order of 400% was observed at quite low frequency of 1 MHz. The highest value of the sensitivity of 520%/Oe was found for the active resistance: Linear sensitivities of 0.023 Ω/˚ and 0.05 Ω/˚ were observed for reasonably low fields of 240 and 275 A/m respectively for small angles, where planar GMI elements are less effective.

“…form distribution is the key issue for the high sensitivity of the sensors. The electroplating parameters, such as current density, pH value, the concentration of the electrolyte for the deposition to achieve optimal composition of Ni 79 Fe 21 have been widely investigated [10][11][12]. In the deposition of composite wire, the copper wire was cleaned with acid to remove the surface oxidation before permalloy film deposition.…”
