Domain wall mobility in co-based amorphous wire

摘要

Dynamics of the domain wall between opposite circularly magnetized domains in amorphous cylindrical samplewith circular easy direction is theoretically studied. The wall is driven by DC current. Various mechanisms which influencethe wall velocity were taken into account: current magnitude, deformation of the mowing wall, Hall effect, axiallymagnetized domain in the middle of the wire. Theoretical results obtained are in a good agreement with experiments on Cobasedamorphous ferromagnetic wires.
