Abstract :
Summary form only given. In annealed Co-based amorphous samples in open air, giant magnetoimpedance (GMI) exhibits a step-like change as a function of the applied magnetic field, which reveals the excellent sensitivity and linearity for the magnetic field. In this study, we present a GMI DC current sensor using a sample wound in the circular form.
