Chapter
Basic Magnetic and Mechanical Properties of Microwire Composites
Due to the inclusion of magnetic fillers, the polymer composite becomes magnetic, i.e. responsive to the external static or dynamic magnetic field. Although most studies are devoted to the dynamic response of ...

Chapter
Domain Structure and Properties of GMI Materials
The domain structure of a rapidly quenched material is often determined by coupling between magnetostriction and internal stresses frozen in during the fabrication process. Such knowledge of the domain structu...

Chapter
Selection of GMI Wires for Sensor Applications
To search for a GMI material for GMI sensor applications, two main requirements should be satisfied, namely a high GMI ratio (or a large GMI effect) and a high sensitivity to the applied field (or a high magne...
