    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.

    摘要： The present invention relates to a perpendicular recording magnetic head. A main magnetic pole film includes an electrode film and a plated magnetic film. The electrode film includes a Ru film and a conductive magnetic film, and the Ru film, which follows the shape of an inner wall surface of a recess formed in a first non-magnetic film, is adhered to the inner wall surface of the recess or a surface of a second non-magnetic film adhered thereto. The conductive magnetic film is adhered to a surface of the Ru film, thereby following the shape of the inner wall surface of the recess. The plated magnetic film is disposed adjacent the conductive magnetic film, thereby filling up the recess.

    摘要： A biometrics authentication device uses biometrics information for individual authentication, and securely registers biometrics information for an authorized agent other than the principal. Biometrics information for the principal, registered in an IC card, is verified against biometrics information detected by a detection unit, and when biometrics authentication of the principal is satisfactory, biometrics information registration for an authorized agent is performed using the detection unit. Biometrics information for the authorized agent can be registered securely in the card in which is registered the biometrics information for the principal.

    摘要： The present invention relates to a perpendicular recording magnetic head. A main magnetic pole film of a perpendicular recording element is a plated film formed on an electrode film and having a small width portion and a large width portion. The small width portion is a portion for emitting a perpendicular magnetic field from a front end thereof, while the large width portion is portion being continuous with a rear end of the small width portion and having an increased width. The electrode film is different in film thickness between beneath a portion of the plated film forming at least the front end of the small width portion and beneath a portion of the plated film forming the large width portion.
