It exhibits a strong magnon-microwave photon coupling with a sphere of yttrium iron garnet (YIG). The average gyromagnetic ratio (γ/2π) and coupling strength (g/2π) achieved are 2.7 MHz/Oe and 11.14 ...

In 2020, Li et al. explored how the surface morphology, from zigzag edge to bearded edge, influences the one-way self-guiding transmission performances of topological honeycomb gyromagnetic PhC (Li et ...
