    摘要： A read sensor of the current-perpendicular-to-the-planes (CPP) type includes a sensor stack structure formed in a central region between first and second shield layers which serve as leads for the read sensor; insulator layers formed in side regions adjacent the central region; seed layer structures formed over the insulator layers in the side regions; and hard bias layers formed over the seed layer structures in the side regions. The hard bias layers are made of a nitrogenated cobalt-based alloy, such as nitrogenated cobalt-platinum (CoPt). Suitable if not exemplary coercivity and squareness properties are exhibited using the nitrogenated cobalt-based alloy. The hard bias layers may be formed by performing an ion beam deposition of cobalt-based materials using a sputtering gas (e.g. xenon) and nitrogen as a reactive gas.

    摘要： A magnetoresistive sensor having improved pinning field strength. The sensor includes a pinned layer structure pinned by exchange coupling with an antiferromagnetic (AFM) layer. The AFM layer is constructed upon an under layer having treated surface with an anisotropic roughness. The anisotropic roughness, produced by an angled ion etch, results in improved pinning strength. The underlayer may include a seed layer and a thin layer of crystalline material such as PtMn formed over the seed layer. The magnetic layer may include a first sub-layer of NiFeCr and a second sub-layer of NiFe formed there over. The present invention also includes a magnetoresistive sensor having a magnetic layer deposited on an underlayer (such as a non-magnetic spacer) having a surface treated with an anisotropic texture. An AFM layer is then deposited over the magnetic layer. The magnetic layer is then strongly pinned by a combination of exchange coupling with the AFM layer and a strong anisotropy provided by the surface texture of the underlayer. Such a structure can be used for example in a sensor having a pinned layer structure formed above the free layer, or in a sensor having an in stack bias structure.

    摘要： A magnetoresistive sensor having a magnetically anisotropic pinned layer structure. The pinned layer structure is formed over a seed layer having a surface that has been treated to texture the surface of the seed layer with an anisotropic roughness. This anisotropic roughness induces the magnetic anisotropy in the pinned layers. The treated seed layers also allow the pinned layer to maintain robust pinning without the need for a thick AFM layer, thereby reducing gap size.

    摘要： A reinforced composite structure is disclosed comprising at least a reactive resin, thermosetting system or other suitable resin composition sandwiched between two metal, thermoplastic or ceramic substrate materials. The structure can also be modified through the addition of one or more fabrics, metallic meshes, fibers, polymer spacers or other suitable materials positioned within the resin composition and sandwiched between the substrate materials. The resulting structure comprises a composite with reduced thickness and weight as compared to solid metal panels of corresponding flexural strength. The composition of the structure also allows for the tailoring of the properties to affect sound abatement, insulation, strength, and toughness among other characteristics. The structure can be formed and cut to shape to fit any of a number of suitable applications such as ceiling tiles and bulkhead panels in marine vessels.
