外镀铜层玻璃包裹丝的巨磁阻抗效应
Giant magneto-impedance on glass-coated microwires with copper layer
摘要
Abstract
The amorphous wires of nominal compositions Fe73.0 Cu1.0 Nb1.5 V2.0 Si13.5 B9.0 were prepared by glass-coating melt-spinning method. Then, the wires were annealed at 480~650 ℃ for 30 min in nitrogen atmosphere. The composite wires with copper layer using electroless deposition were produced, a thin layer of copper deposited onto the microwires annealed at 570 ℃. The morphology of composite microwires was observed using SEM. The giant magnetoimped-ance effect on the samples was investigated. The results show that soft magnetic properties of the specimen can improve its MI ratio. The electromagnetic interactions between the ferromagnetic core and the copper layer can also affect MI ratio.关键词
