Abstracts

EN

The presented article deals with a model of magnetic reversal in conducting lamination with a one central ferromagnetic layer and two outer non-ferromagnetic layers. Considering a single rigid 180° domain wall spreading through the axially magnetized ferromagnetic layer the calculation of induced eddy currents in lamination is performed. The dependence of single domain wall mobility on the thickness of ferromagnetic layer is displayed. The effect of non-homogeneous magnetic field intensity generated by eddy currents is also discussed.
