Single domain wall dynamics in thin magnetic wires

Abstract Here we present the low-field domain wall dynamics in thin magnetic wires. It is shown that the domain wall dynamics at low applied fields is described by the power law. The role of all parameters in the domain wall dynamics was studied in a wide temperature range. The power exponent β , which should reflect the changes of the domain wall shape due to its pinning on the local defects, is almost temperature independent. This points to the fact the mechanism of the domain wall pinning does not change with the temperature in the temperature range 77–350 K. This fact is also consistent with the temperature dependence of the switching field H sw .
