First order and second order magnetic anisotropy constants were obtained from polar magneto-optical Kerr effect magnetometry. Analyzing these constants values we conclude that a thickness induced spin reorientation transition from out-of-plane state to in-plane state occurs through an easy-cone magnetization state. Exploiting the magneto-optical imaging technique for out-of-plane magnetized states the magnetization reversal process was examined and the evolutions of magnetic domains in external magnetic field were observed. Magnetization reversal dynamics in indirect process indicates a significant change of magnetization rate in comparison with direct process. At the same time magnetic domains observation reveal a formation of narrow stripe domains (NSDs) and dendrite like structures depending on CoFeB thickness[1]. These NSDs structure could be applicable for controlled spin wave propagation.<\/p>\n<p style=\"text-align: justify;\">Reference:<br \/>\n[1] A.K.Dhiman, T. Dohi, W. Dobrogowski, Z. Kurant, I.
