摘要
The performance of the current sensor based on giant magnetoimpedance (GMI) effect in amorphous ribbon has been tested. The toroidal-type ribbon after field annealing shows a maximum GMI ratio of 16% at 100 kHz measuring frequency with corresponding field sensitivity of 35% Oe(-1). The sensor output voltage increases with applied current up to 1 A with a good linearity. The sensor performance for DC current is better than that for AC current. (C) 2003 Elsevier Science B.V.
