摘      要：The BeCu/Insulator/CoP composite wires were prepared by electroless–deposition on insulated BeCu wire. The composite wire constructs a serial LC resonant element by itself. Due to the LC resonance, very large high-frequency magneto-reactance effect is observed at near the LC resonance frequency, and the maximal magneto-reactance ratio for the composite wire with length of 5 cm is 1.08×107% at 58924500 Hz. The LC resonance frequency decreases with the increasing length of the composite wire. The practical working frequency, at which the very large high-frequency magneto-reactance effect is observed, can be controlled through controlling the LC resonance frequency. The LC resonance mechanism is also analyzed.
