摘要： Magnon frequency combs have garnered significant attention due to their wide-ranging potential applications, primarily generated by the interplay between spin waves and oscillating magnetic textures. Developing an easily achievable magnon frequency comb with directly tunable comb spacing is pivotal for broadening its utility. In this study, we engineered a Bloch-type magnetic domain wall with a stable structure and fixed position by employing a dual-pinning approach utilizing artificial structural defects and stray fields. We established a magnetic domain wall oscillation mode based on resonant Larmor precession, serving as the foundation for a magnon frequency comb derived from magnetic domain walls. By leveraging the locally distributed Oersted field generated by an alternating current, we achieved precise control over the oscillation frequency of the domain wall, thereby realizing a magnon frequency comb with directly tunable comb spacing. The insights from this research offer a promising shortcut for exploring frequency combs based on the interaction between spin waves and magnetic domain walls.
