摘要：

The circular magnetization reversal process in a long ferromagnetic wire with a non-ferromagnetic conductive cover is theoretically analysed. The model of a single thin rigid 180 degrees domain wall (DW) is used so that the wire is divided crosswise into two magnetic domains with opposite circular magnetization. It is presumed that after switching on direct electric current in the wire, the circular magnetization reversal occurs by means of the DW movement through the wire. The induced electric field and the eddy current power losses in all conductive parts are calculated in the model, from which the DW rnobility is determined. It is shown that DW mobility is very sensitive to the thickness and the conductivity of the non-ferromagnetic cover. An experimental procedure for measuring DW mobility through the non-ferromagnetic conductive cover is proposed. (C) 2014 Elsevier B.V. All rights reserved
