本研究通过角度依赖铁磁共振和直流磁化测量，揭示了YbMn$_\ ext{6}$Sn$_\ ext{6}$沿c轴的硬轴单轴各向异性及ab面内的双重各向异性，后者源于生长诱导的对称性破缺。

RMn$_\ ext{6}$Sn$_\ ext{6}$（R = 稀土）kagome磁体家族展现出丰富的磁态以及非常规的电子和磁性质。尽管这些材料的静态磁性质已被广泛研究，但其磁化动力学仍探索较少。在此，我们利用角度依赖的铁磁共振（FMR）光谱和直流磁化测量，研究了铁磁YbMn$_\ ext{6}$Sn$_\ ext{6}$的磁各向异性和动态磁化。FMR的角度依赖性揭示了沿晶体学c轴的预期单轴各向异性，该轴为全局磁硬轴。此外，我们识别出ab面内显著的双重各向异性，这通过角度依赖的直流磁化测量独立证实。观察到的ab面内单轴各向异性表明，磁响应中预期的六重旋转对称性发生破缺，这归因于生长诱导的各向异性。
英文摘要
The RMn$_\text{6}$Sn$_\text{6}$ (R = rare earth) family of kagome magnets exhibits a rich variety of magnetic states and unconventional electronic and magnetic properties. While the static magnetic properties of these materials have been extensively investigated, their magnetization dynamics remain less explored. Here, we investigate the magnetic anisotropy and dynamic magnetization of ferromagnetic YbMn$_\text{6}$Sn$_\text{6}$ using angle-dependent ferromagnetic resonance (FMR) spectroscopy and DC magnetization measurements. The angular dependence of FMR reveals the expected uniaxial anisotropy along the crystallographic c-axis, which is the global magnetically hard axis. In addition, we identify a pronounced twofold anisotropy within the ab-plane, which is independently confirmed by angle-dependent DC magnetization measurements. The observed uniaxial anisotropy in the ab-plane indicates a breaking of the expected sixfold rotational symmetry in the magnetic response that is attributed to growth induced anisotropy.
