Abstract

Composite wires of 100 μ insulated CuBe wire plated with a layer of NiFeB were produced by electroless-deposition, and their magnetic properties were studied. The results showed that a good magneto-impedance (MI) effect can be obtained at relatively low frequency. The largest MI ratio (ΔZ/Z)max obtained is 250% at 500 kHz. Magneto-resistance effect was also observed at low frequency, with the (ΔR/R)max observed to be -8.5% at 540 Hz and 38.7% at 10 kHz. Results are discussed, and the equivalent resistance and inductance as the result of the NiFeB layer are taken into account.
