abstract = "The paper presents three-dimensional micromagnetic simulation of the magnetization reversal process of permalloy film with additional relief elements of step-like shape made of the same material. It is shown that in the course of magnetization reversal in a constant magnetic field, the initial magnetization distribution containing a C-shaped domain wall is transformed into a magnetization reversal zone filled with vortex structures. In this case, the magnetization reversal dynamics becomes irregular. The peculiarities of the dynamics of the magnetization reversal zone (change in magnetization reversal rate, temporary or final cessation of motion) are revealed for different types of surface relief elements (strips, linear or two-dimensional arrays of rectangular parallelepipeds of different sizes). Visualization methods of vortex structures are described.",
