    摘要： An example method for manufacturing a magneto-resistance effect element having a magnetic layer, a free magnetization layer, and a spacer layer includes forming a first metallic layer and forming, on the first metallic layer, a second metallic layer. A first conversion treatment is performed to convert the second metallic layer into a first insulating layer and to form a first metallic portion penetrating through the first insulating layer. A third metallic layer is formed on the first insulating layer and the first metallic portion. A second conversion treatment is performed to convert the third metallic layer into a second insulating layer and to form a second metallic portion penetrating through the second insulating layer.

    摘要： An example magnetoresistive element includes a first magnetic layer whose magnetization direction is substantially pinned toward one direction; a second magnetic layer whose magnetization direction is changed in response to an external magnetic field; and a spacer layer provided between the first magnetic layer and the second magnetic layer. At least one of the first magnetic layer and the second magnetic layer has a magnetic compound that is expressed by M1aM2bXc(where 5≦a≦68, 10≦b≦73, and 22≦c≦85). M1 is at least one element selected from the group consisting of Co, Fe, and Ni. M2 is at least one element selected from the group consisting of Ti, V, Cr, and Mn. X is at least one element selected from the group consisting of N, O, and C.

    摘要： A blood-pressure sensor includes a substrate, a first electrode, a magnetization fixed layer, a nonmagnetic layer, a magnetization free layer, and a second electrode. The substrate is bent to generate a tensile stress at least in a first direction. The first electrode is provided on the substrate. The magnetization fixed layer has magnetization to be fixed in a second direction, and is provided on the substrate. The nonmagnetic layer is provided on the magnetization fixed layer. The magnetization free layer has a magnetization direction which is different from the first direction and from a direction perpendicular to the first direction. The second electrode is provided on the magnetization free layer.
