IPC: G01R33/09
Filed: 1994-04-28
Abstract: PURPOSE:To eliminate the characteristic variation of a magnetoresistive effect element caused by the variation of the magnetized direction of a hard film by impressing magnetic fields leaking out from a single hard film upon a pair of magnetoresistive effect films as opposite bias magnetic fields by using a high permeability magnetic film which is magnetically coupled with the hard film. CONSTITUTION:Bias magnetic field guiding films 6a, 6b, and 6c are formed of high permeability magnetic materials and magnetic fields leaking out from a hard film 2 are impressed upon a magnetoresistive effect film 1a by means of the film 6a. The film 6b impresses a bias magnetic field upon a magnetoresistive effect film 1b by changing the direction of the magnetic field and the film 6c acts to return the magnetic field to the hard film 2. Since such a magnetic circuit is formed, bias magnetic fields which are opposite to each other in direction and have the same magnitude are impressed upon the films 1a and 1b from a direction perphendicular to the elongated direction of the magnetic fields.
