Research Of Giant Magnetoimpedance Effect Based In Current Sensor

In this thesis, we mainly reviewed the history of GMI effect, introduced the origin of GMI, the methods in researching GMI effect, the factors that influenced on GMI effect, and the experimental analysis on the noble phenomenon of GMI effect. We designed two current sensors based on GMI effect, the amorphous materials such as CoZrB are used to develop spiral structure probe and array structure probe, and then measuring current is followed, meanwhile, we had great prospect in the future work.
