摘要： A nonmagnetic material-noncontact layer forming a fixed magnetic layer is formed using CoFe, a nonmagnetic material-contact layer is formed using Co, and an NOL (Nano-Oxide Layer) is provided between the nonmagnetic material-noncontact layer and the nonmagnetic material-contact layer. In addition, the average film thickness of the nonmagnetic material-contact layer is set in the range of 16 to 19 Å. Accordingly, compared to a three-layered structure composed of CoFe, an NOL, and CoFe or a three-layered structure composed of Co, an NOL, and Co, which has been conventionally used, the rate (ΔR/R) of change in resistance and the unidirectional exchange bias magnetic field (Hex*) can both be improved.
摘要翻译：使用CoFe形成形成固定磁性层的非磁性材料非接触层，使用Co形成非磁性材料接触层，在非磁性材料 - 非接触层和非磁性材料 - 非接触层之间设置NOL（纳米氧化物层）接触层。此外，非磁性材料接触层的平均膜厚设定在16〜19的范围内。因此，与通常使用的CoFe，NOL，CoFe或由Co，NOL，Co构成的三层结构体构成的三层结构相比，变化率（ΔR/ R）电阻和单向交流偏置磁场（Hex *）都可以提高。

摘要： A magnetic sensing element includes a free magnetic layer having a three-layer structure including a first enhancement layer in contact with a nonmagnetic material layer, a second enhancement layer, and a low-coercivity layer. The second enhancement layer has a lower magnetostriction coefficient λ than the first enhancement layer. If such an enhancement layer having a bilayer structure is used, rather than a known monolayer structure, and the second enhancement layer has a lower magnetostriction coefficient λ than the first enhancement layer, the rate of change in magnetoresistance of the magnetic sensing element can be increased with no increase in the magnetostriction coefficient λ of the free magnetic layer.

摘要： A sensor substrate includes a plurality of piezoresistance elements. The electrical resistance of each piezoresistance element changes in accordance with an amount of displacement of a displacement portion displaced by an external load applied through a pressure receiving unit. A base substrate supports the sensor substrate. The sensor substrate and the base substrate each include a support supporting the displacement portion such that the displacement portion can be displaced and a plurality of electrically connecting portions electrically connected to the plurality of piezoresistance elements. The supports of the sensor and base substrates are joined to each other and the plurality of electrically connecting portions of the sensor and base substrates are joined to each other. Furthermore, in each of the sensor and base substrates, either the support or the plurality of electrically connecting portions or both extend to the periphery of the sensor substrate or the base substrate.

摘要： A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe—M—O alloy, an Fe—M—T—O alloy or an NI—Fe—X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.
