Magneto-optical study of the magnetization reversal process of Fe nanowires

摘要: We discuss results of magneto-optical Kerr effect (MOKE) measurements performed on a thin Fe film 13 nm thickness, which has been patterned into periodic arrangement nanowires by means optical interference lithography. The resulting array consist stripes having width 150 and periodicity 300 nm. MOKE hysteresis loops are measured within magnetic fields aligned in different directions, both parallel perpendicular with respect to the direction as well for various angles between. A particular longitudinal measurement allows us identify transverse component magnetization nanowires. From this angle magnitude vector derived. For non-parallel alignment external field, plateau region two coercive Hc1 Hc2, is discussed from an anisotropic pinning behaviour domains directions along
