Topological-charge-driven reversal of ferromagnetic rings via 360 â^~ domain-wall formation
Oyarce, A. L. G.; Trypiniotis, Theodossis; Roy, P. E.; Barnes, C. H. W. (2013)We study the reversal mechanism between opposite closed flux states of ferromagnetic nanorings driven by an azimuthal magnetic field. The reversal proceeds via the formation of 360â^~ domain walls, and we show that the ...
