Micromagnetic Study of Magnetization Orientation Dependence of Magnetization Reversal Mechanism in Magnetic Nanowires

Magnetization orientation dependence of the magnetization reversal mechanism in magnetic nanowires with different diameters was investigated by micromagnetic simulation. The results show that the theoretical model of finite nanowire differs from that of infinite nanowire. It was found that the reversal mechanism of finite nanowires significantly depends on θ, the angle between the field direction and wire length for almost all diameters. Though the reversal mechanism varies with the nanowire diameter, the reversal mode changes from the complicated reversal to the coherent rotation in all diameter range with the angle increasing from 0°to 90°.
