Abstract

Soft magnetic properties of melt spun Co-based amorphous wires fabricated by photo lithography and wet etching processes were examined with length (1-10 mm), width (200 μm-6 mm), and thickness (3-20 μm) variation. The value of coercivity Hc, susceptibility κ and squareness were extracted from M-H curve measured using a vibrating sample magnetometer (VSM). Monotonic increase of these values with aspect ratio of the wires was observed, which shows that the magnetic properties of the samples were largely determined by shape anisotropy. The observed phenomena were explained by the competition between domain wall pinning and demagnetizing field. It was shown that, when the sample's residual stress is constant, demagnetizing factor largely determines its magnetic properties.
