Technical Paper


The magnetization reversal process for elliptical and rectangular permendur (CoFe) nanostructures were compared using micromagnetic simulations. Single domain states were observed in 10 nm thick elliptical and rectangular nanomagnets. The magnetization reversal along the major and minor axis in 60 nm thick elliptical nanomagnets occurred through the formation of double vortex states. In rectangular nanomagnets, it occurred through the formation of single vortex state along 225 nm and double vortex state along 335 nm.
