Manipulation of domain propagation dynamics with the magnetostatic interaction in a pair of Fe-rich amorphous microwires

We studied the domain wall dynamics in a system of two magnetostatically interacting Fe-rich glass coated amorphous microwires paying attention on the influence of the interaction and the external tensile stress on the velocity of the domain wall propagation. We measured and analyzed numerically the dependence of the shape of the hysteresis loops on the frequency of the applied field considering its origin related with the finite domain wall velocity. The critical condition for the disappearance of the plateau on the hysteresis loops separating two remagnetization events in a system of two microwires was investigated. (C) 2013 AIP Publishing LLC.
