Domain Wall Dynamics of Wires in Perpendicular Magnetic Field.

The paper deals with the influence of an external perpendicular magnetic field on a domain wall motion in glass-coated amorphous microwires. The dependence of the domain wall velocity on the external axial magnetic field is measured at the presence of a perpendicular magnetic field. Subsequently, the microwire is rotated in a perpendicular field. The results show that the rotation of the microwire in the perpendicular magnetic field increases the domain wall velocity at certain rotations. At the same time, it shows that the mobility of the domain wall varies periodically with the rotation of a microwire. The results are discussed in terms of perpendicular magnetic anisotropy.
