Among them, FeCoSiBNi amorphous magnetic films show a good impedanceby melt-spun method, one of the rapid solidification process. Ribbon shape wires were made from the films, and let themannealed in DC magnetic field to increase the maximum Giant Magneto Impedance ratio. Field annealing decreases thestress and changes the effective anisotropy. Thus, we can find that the impedance change (200.47 %) is improved andthe fabricated magnetic wire has characteristics of good sensor element. 한국센서학회 CoFeSiBNi 아몰퍼스 합금의 자기-임피던스 효과 Magneto-impedance effect of CoFeSiBNi amorphous magnetic films Article 2 센서학회지, v.16, no.5, pp.389 - 393 센서학회지 16 5 389 393 kci ART001080374 MI effect soft magnetic amorphous magnetic film magnetic sensor skin effect Annealing
