摘要
We have investigated the giant magnetoimpedance (GMI) effect in fibers of different soft magnetic materials and in Permalloy wires. The have been tested in the radio frequency (rf) by measuring the voltage drops in different parts of the circuit. The wires have been tested in the ultra high frequency (uhf) range, by measuring the transmission coefficient s(21) of coaxial lines having as central conductor a HyMu80 wire. The two methods provided quite similar results showing strong GMI effect for very different magnetic samples.
