Influence of an axial field on the movement of the boundary between circular domains in stress annealed Co-Fe-Si-B amorphous wire
The influence of an axial field on the velocity of a single boundary between two circular domains (CDW) was studied in a stress annealed amorphous Co68.2 Fe4.3 Si12.5 B15 wire. The velocity of the CDW depends on the magnitude and orientation of the axial field and it is also different for parallel and anti-parallel direction with respect to the current flow. At lower currents the observed behavior can be explained as a combined effect of helical anisotropy (with a very small deviation of the easy axis from the ideal circular direction) and of non-diagonal components of the resistivity tensor (the so called “domain drag effect”).
