Abstract The interaction between a magnetic domain wall and a pinning site is explored in a planar nanowire using micromagnetics to reveal perturbations of the pinning energetics for propagating domain walls. Numerical simulations in the high damping ’quasi-static’ and low damping ’dynamic’ regimes are compared and show clear differences in de-pinning fields, indicating that dynamical micromagnetic models, which incorporate precessionally limited magnetization processes, are needed to understand domain wall pinning. Differences in the micromagnetic domain wall structure strongly influence the pinning and show periodic behaviour with increasing applied field associated with Walker breakdown. In the propagating regime pinning is complicated.

Domain Wall Structure

The reversal process of an exchange spring trilayer was studied by micromagnetic simulation, simulating the hysteresis loop and magnetic domain wall structure of a soft/hard/soft ferromagnetic exchange spring. The exchange spring effect was observed, determining the chirality of its spiral magnetization configuration. By simulation of the domain wall structure, we find that reversal nucleation emerge simultaneously in either surface of two soft layers and the magnetic moments of hard layer start rotation at reversible stage.
