Abstract:
In this work, we investigate the field-driven domain wall motion in bilayer piezoelectric nanostructure under the influence of inertial and crystallographic defects. We examine the magnetization dynamics in the framework of the generalized Landau-Lifshitz-Gilbert equation of micromagnetism that includes the effects of nonlinear dissipations, inertia, and piezo-induced strains. The obtained analytical results explicate the threshold and Walker-type breakdown estimates of an applied magnetic field in both the steady-state and precessional regimes. Finally, the interaction of inertial, nonlinear dissipations, and piezo-induced strains and their physical implications are discussed analytically and numerically in both the dynamical regimes.
