MAGNETIC IMPEDANCE EFFECT ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To resolve such problem of a conventional magnetic impedance effect element that the sensitivity in detection of a magnetic field drops if the aspect ratio of a magnetosensitive part is made small. SOLUTION: The sensitivity in detection of a magnetic field can be enhanced in case that the aspect ratio of a magnetosensitive part 12 is made small, by superposing direct current components Idcon drive AC currents Iac, and applying a DC bias field B in the width direction of the magnetosensitive part 12.
