Abstract
Magnetoinductance and giant magnetoimpedance (GMI) sensors have greatly benefited from the development of amorphous wires. These soft ferromagnetic substances exhibit exquisite sensitivity (in the nT range) and wide bandwidth (MHz) in thin film structures. Combining these properties with surface wave technology produces passive, wireless sensors
