<p>Apparatus is provided for detecting the direction of magnetic field using a magnetoresistive device which comprises a stationary bias magnet magnetized in the direction of its thickness so that the pole faces of the magnets are continuous to each other, lie in a common plane and are of alternating polarity; and a magnetoresistive element which is formed of at least two ferromagnetic film strips arranged substantially perpendicular to each other to define perpendicular main current conducting paths, the strips being disposed on a substrate which is parallel with and adjacent to the pole faces, whereby a bias flux is applied to the magnetoresistive element from the stationary bias magnet at a predetermined angle.</p> |
