摘要： A sputtering target consisting essentially of Mn and at least one kind of R element selected from a group of Ni, Pd, Pt, Co, Rh, Ir, V, Nb, Ta, Cu, Ag, Au, Ru, Os, Cr, Mo, W, and Re. The sputtering target, at least as a part of target texture, comprises one member selected from a group of an alloy phase and a compound phase formed between the R element and Mn. In addition, oxygen content in the target is 1 weight % or less (including 0). With such a sputtering target, an anti-ferromagnetic material film consisting of RMn alloy excellent in corrosion resistivity and thermal performance can be stabilized in its film composition and film quality. By employing the anti-ferromagnetic material film, when an exchange coupling film is formed by stacking the anti-ferromagnetic material film and the ferromagnetic material film, sufficient exchange coupling force is obtained stably. Such an exchange coupling film can be used in a magneto-resistance effect element and the like.

摘要： A magnetoresistance effect device comprises a magnetic multi-layer film having at least an antiferromagnetic film, a first ferromagnetic film, a non-magnetic film, and a second ferromagnetic film formed in the order on the front surface portion of the substrate, the magnetic multi-layer film having giant magnetoresistance effect, at least the second ferromagnetic film having a shape corresponding to a magnetic field detecting portion. The bias magnetic field applying films are disposed on a conductive film of the magnetic multi-layer film at outer portions of both edge portions of the magnetic field detecting portion of the magnetoresistance effective film. Alternatively, the second ferromagnetic film has a first portion corresponding to the magnetic field detecting portion and a second portion corresponding to the outer portions of both the edge portions of the magnetic field detecting portion, the film thickness-of the second portion being smaller than the film thickness of the first portion. The bias magnetic field applying films are formed at the outer portions of both the edge portions of the magnetic field detecting portion of the second ferromagnetic film. With the reversely structured magnetoresistance effect film and the laminate positions of the bias magnetic field applying films, in addition to suppressing the reproduction fringe and Barkhausen noise, the decrease of contact resistance, the suppression of insulation detect, and good linear response characteristic can be accomplished.
