Micromagnetic simulations of semielliptical permalloy elements

Magnetic spin configuration of patterned semielliptical permalloy elements useful for transportation of biofunctionlized magnetic particles was investigated by micromagnetic simulations. A demagnetized state at zero field shows a stable vortex state around the center. Application of 100Oe field alon...

Beschreibung
Zusammenfassung:	Magnetic spin configuration of patterned semielliptical permalloy elements useful for transportation of biofunctionlized magnetic particles was investigated by micromagnetic simulations. A demagnetized state at zero field shows a stable vortex state around the center. Application of 100Oe field along a short axis of semiellipse was found to be sufficient to completely saturate the element along the field direction.
