    摘要： A GMR element part is formed of a laminated structure which comprises at least one pair of ferromagnetic layers and a nonmagnetic intermediate layer interposed between the pair of ferromagnetic layers. Signal magnetic field detecting ferromagnetic layers will be optionally disposed one each outside the pair of ferromagnetic layers. The GMR element part consists of a laminated structure which is provided with one pair of GMR ferromagnetic layers opposed to each other across a nonmagnetic intermediate layer or a laminated structure which is provided with one pair of GMR ferromagnetic layer opposed to each other across a nonmagnetic intermediate layer and at least one low-permeability ferromagnetic layer disposed there between through the medium of a nonmagnetic intermediate layer. The GMR element part functions as a read head for sensing the resistance which is varied when signal magnetic fields of mutual opposite directions are applied to the pair of GMR ferromagnetic layers and displaying a differential detection type output response. A granular type ferromagnetic intermediate layer will be used as the GMR element part.

    摘要翻译： GMR元件部分由层叠结构形成，该叠层结构包括至少一对铁磁层和介于一对铁磁层之间的非磁性中间层。 信号磁场检测铁磁层将可选地布置在一对铁磁层的外侧。 GMR元件部分由层叠结构构成，该叠层结构具有一对跨越非磁性中间层彼此相对的GMR铁磁体层或层叠结构，该层叠结构具有跨越非磁性中间体彼此相对的一对GMR铁磁层 层和至少一个通过非磁性中间层的介质设置在其间的低磁导率铁磁层。 GMR元件部分用作读取头，用于感测当相互相反方向的信号磁场施加到一对GMR铁磁层并且显示差分检测型输出响应时变化的电阻。 将使用粒状铁磁中间层作为GMR元件部分。

    摘要： A magnetoresistive head is disclosed which uses a crystalline soft magnetic film as an undercoat for a giant magnetoresistive film provided with at least one pair of ferro-magnetic films opposed to each other across a nonmagnetic intermediate layer or for an anisotropically magnetoresistive film. The crystalline soft magnetic film comprises a film which has as a main component thereof at least one element selected from the group consisting of Ni, Fe, and Co and simultaneously incorporates therein at least one element selected from the group consisting of Nb, Mo, V, W, Ti, Zr, Hf, and Ta and at least one element selected from the group consisting of Cr, Rh, Os, Re, Si, Al, Be, Ga, and Ge.
