磁振子和声子的杂化在新兴的混合磁振子学领域中发挥着关键作用，因为它结合了磁性的高可调谐性和力学的长寿命，用于全面的相干信息处理。近年来，由于薄膜体声波在高频下具有较长的寿命，引起了人们越来越多的兴趣。然而，这种声子模式的独特的多模性质尚未被利用作为相干信息处理的重要资源。在这封信中，我们研究的同时杂交的多个高泛音体声波共振与磁振子和微波模式。所展示的多模杂交使我们能够观察到相干脉冲回波，为混合磁振子的基础研究和实际应用提供了机会。
The hybridization of magnons and phonons is playing a critical role in the emerging field of hybrid magnonics because it combines the high tunability of magnetism with the long lifetime of mechanics for comprehensive coherent information processing. Recently there has been increasing interest in thin-film bulk acoustic waves because of their long lifetimes at high frequencies. However, the unique multimode nature of such phonon modes has not been exploited as an important resource for coherent information processing. In this Letter we study the simultaneous hybridization of multiple high-overtone bulk acoustic resonances with a magnon and a microwave mode. The demonstrated multimode hybridization allows us to observe coherent pulse echoes, opening opportunities for both fundamental studies and practical applications of hybrid magnonics.
