Abstract

The motion of a magnetic domain wall in a submicrometer magnetic wire was detected by use of the giant magnetoresistance effect. Magnetization reversal in a submicrometer magnetic wire takes place by the propagation of a magnetic domain wall, which can be treated as a “particle.” The propagation velocity of the magnetic domain wall was determined as a function of the applied magnetic field.

The samples were prepared by using lift-off techniques as follows: First a 0.1 μm thickness of ZEP520 resist was spin-coated on a Si(100) substrate. After the pattern of wire was exposed by an electron-beam writer the resist was developed. The NiFe(400 Å)/Cu(200 Å)/NiFe(50 Å) trilayer film was deposited on the patterned mask by electron-beam evaporation in a vacuum of 1 × 10 –8 Torr. The wire with trilayered structure was obtained after the resist mask was removed. Because of the large Cu-layer thickness the interlayer exchange coupling between the NiFe layers is negligible. The width of the wire is 0.5 μm and the sample has four current-voltage terminals where the voltage is probed over a distance of 2 mm.
