    Coherent harmonic generation of magnons in spin textures by Guibin Lan, Kang-Yuan Liu, Zhenyu Wang, Fan Xia, Hongjun Xu, Tengyu Guo, Yu Zhang, Bin He, Jiahui Li, Caihua Wan, Gerrit E. W. Bauer, Peng Yan, Gang-Qin Liu, Xin-Yu Pan, Xiufeng Han, Guoqiang Yu

    Published 2025-01-01
    “…Numerical simulations indicate that the harmonic generation by microwaves below the ferromagnetic resonance frequency is associated with the nonlinear mixing of spin waves by magnetization structures at the film edge. Our finding of geometry-induced magnon harmonic generation constitutes a new way to generate magnon combs with coherent high-order harmonics and may pave the way for magnon-based information processing and quantum sensing applications.…”
