High-Sensitivity GMR Sensor Using Domain-Wall Oscillation
Journal of the Magnetics Society of Japan
The high sensitivity detection of magnetic fields was demonstrated using the oscillatory domain-wall displacing method for a GMR sensor. A micro-wire with a width of 30 µm and a length of 200 µm of a spin valve film, Al(20 nm)/MnIr(20 nm)/CoFe(3 nm)/Cu(2.2 nm)/CoFeB(10 nm), was fabricated as a magnetic sensor device. The domain walls in the free layer, whose easy axis was perpendicular to the wire, were oscillatorily displaced by an alternating magnetic field produced by a current with 140 kHzdoi:10.3379/msjmag.1002r0006 fatcat:nzc4fsgr6bdy7gef3qk7fmaety
