Study of magnetization reversal in Néel and Bloch regime of nickel and permalloy stripes using Kerr microscopy

We present a systematic study of the magnetization reversal nickel and permalloy micro-stripes with Neel Bloch domain walls using Kerr microscopy. Magnetic field driven propagation was observed from higher width to lower stripes for magnetic fields applied along length micro-stripes. Stripe like domains were nucleation starting in region followed by their regions The comparison N\'eel wall regime showed density both stripes.
