    摘要： The present invention is directed to a magnetic transducer element with outstanding productivity, with which the track width can be defined to a high degree of accuracy and required magnetic characteristics can be reliably imposed upon the central active area. Laminated films which generate a magnetoresistance effect, a magnetic domain control film, which applies a magnetic bias to the laminated films and a pair of lead conductor films are provided. The laminated films and the magnetic domain control film are laminated to each other to constitute a central active area. The lead conductor films terminate the side end surfaces of the central active area at the two sides in direction running at a right angle to direction of the lamination of the central active area.

    摘要： In a magnetoresistance effect element, a pinning layer (antiferromagnetic layer) has a composition of Ru--Mn or Ru--M--Mn where M represents at least one selected from Rh, Pt, Pd, Au, Ag, and Re, and impurity concentrations of the pinning layer are regulated. Accordingly, there can be provided the magnetoresistance effect element having a magnetic multilayered film which is excellent in corrosion resistance, thermal stability and magnetic field sensitivity and has a large MR change ratio, as well as a magnetoresistance device, such as a magnetoresistance effect type head or the like, using such a magnetoresistance effect element.
