| Abstract: | The giant magnetic impedance effects(GMI) of Co-based amorphous wires were measured.The effects of frequency and external magnetic field H on GMI were investigated.It was found that GMI was more than-50% at H=100 mT with frequencies range from 6 MHz to 21 MHz,and about-40% with magnetic field range from 30 mT to 40 mT. |
