چکیده انگلیسی
The authors use micromagnetic simulation to investigate the magnetization reversal process of a new ferromagnetic submicron dot structure composed of a lateral gradient magnetization. The reversal process in this new structure begins at the both edges along and is perpendicular to the applied magnetic field due to introducing a demagnetizing field from the interface of the magnetization gradient. This leads to a two-stage nucleation process. Based on the analytical results, a novel submicron structure with a quarter of lateral gradient magnetization is proposed to control the chirality of a vortex, which is important for applications that use the vortex's chirality.
