Magnetoresistive sensor for measuring magnetic field intensity, has sensitive unit including superposition of layers of ferromagnetic and anti-ferromagnetic materials to obtain magnetic moment

摘要

The sensor has a sensitive unit (4) including superposition of layers of ferromagnetic and anti-ferromagnetic materials to obtain a magnetic moment. Component of the magnetic moment directed in direction of magnetic field to be measured varies reversibly according to intensity of the magnetic field to be measured. The component is directed linearly in an adjustable field range.
