  • Patent number: 9007055
    Abstract: Provided are a self-pinned spin valve magnetoresistance effect film, a magnetic sensor using the same, and a rotation angle detection device. The self-pinned spin valve magnetoresistance effect film has a strong coupling magnetic field in a pinned layer, a small reduction in the change in resistance, and superior resistance to magnetic fields without reducing the coercive force in a first ferromagnetic layer, which is a pinned layer in the film, even when exposed to a strong external magnetic field. By inserting a non-magnetic layer between a ground layer and a pinned layer to form the spin valve magnetoresistance effect film, the self-pinned spin valve magnetoresistance effect film having superior resistance to magnetic fields, a magnetic sensor using the same, and a rotation angle detection device are obtained.

  • Patent number: 8564282
    Abstract: There is provided an angle sensor and angle detection device of high output and high accuracy with a wide operating temperature range. First through eighth sensor units 511, 522, 523, 514, 531, 542, 543 and 534 are produced from spin valve magnetoresistive films that use a self-pinned type ferromagnetic pinned layer comprising two layers of ferromagnetic films that are strongly and anti-ferromagnetically coupled. The respective sensor units are produced via the formation and patterning of thin-films magnetized at angles that differ by 90°, and the formation of insulation films. By using, for the ferromagnetic films, CoFe and FeCo films that have similar Curie temperatures to make the difference in magnetization amount be zero, high immunity to external magnetic fields, a broad adaptive temperature range, and high output are realized.
