Аннотация
The magnetic properties and specific features of giant magnetoimpedance in rapidquenched amorphous wires of composition (Co0.94 Fe0.06 )72.5Si12.5 B15 are investigated. The working interval and sensitivity to changes in an external quasistatic magnetic field have been calculated for the alternating current frequencies from 1 MHz to 1 GHz. Parameters that are optimum for using such wires as sensitive elements in magnetic field sensors have been calculated, and the probe sensitivity to the external magnetic field has been determined. A sensor prototype was designed that, when tested, confirmed the possibility of using the giant magnetoimpedance in sensors based on amorphous CoFeSiB wires for flaw detection.
