  The dynamic behaviors of magnetic domain walls have significant implications
for developing advanced spintronic devices. In this study, we investigate the
intriguing resonance phenomenon within the magnetic domain wall structure and
its profound influence on dynamic motion, focusing on the dissipation
mechanism. By applying a static external magnetic field, we observe a
remarkable amplification of domain wall velocity, surpassing the limitations of
the conventional one-dimensional model. To quantify this enhancement, we
introduce a novel parameter, the distortion variation rate, which captures the
rapid and pronounced changes occurring within the domain wall structure.
Through comprehensive micromagnetic simulations, we establish a robust
relationship between speed and distortion variation rate, thereby validating
our theoretical framework. Our findings provide crucial insights into the
underlying mechanisms governing domain wall dynamics while paving the way for
developing and optimizing next-generation spintronic devices boasting
unparalleled speed and efficiency.
