We report systematic micromagnetic investigation of formation of magnetic domains in perpendicularly magnetized Co/Pt multilayer with the variation in magnetic anisotropy and stack thickness. The lowering of anisotropy makes the domain wall broader and domain formation less efficient. Domain sizeincreases with increasing thickness of the stack to minimize the stray field energy. The minimization of energy of the system due to domain formation makes the M-H loop narrower whereas, lower stack thickness results in a wider loop. The magnetization reversalin this system occurs due tothe nucleation and growth of reverse domains.
