Abstract
Here we report on the domain wall dynamics in amorphous glass-coated FeCuNbSiB microwires measured in the temperature range from 77 up to 400Â K. At low temperatures below 200Â K, the domain wall velocity is proportional to the applied magnetic field. At temperatures above 200Â K, two regions have been found: one with low domain wall mobility at low fields and another one with high domain wall mobility at high fields. The different regions of the domain wall dynamics are treated in terms of the change of the domain wall configuration from transversal to vortex one. Moreover, non-linear regime is shown at low fields at the temperature 373Â K as a result of the domain wall interaction with the local defects.
