发明名称 SELF-PINNED SPIN VALVE MAGNETORESISTANCE EFFECT FILM AND MAGNETIC SENSOR USING THE SAME, AND ROTATION ANGLE DETECTION DEVICE
摘要 <p>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.</p>
