论文摘要
我们研究了非雷诺木元元的微观来源，该来源与蜂窝状抗fiferromagnet中的dzyaloshinskii-moriya相互作用不同。关键成分是根据粘结方向的对称各向异性交换相互作用，这导致在交错的抗抗铁磁有序下产生山谷型非型磁蛋白激发。此外，我们发现这种类型的非倒数磁蛋白表现出特殊的磁场响应。非偏置方向可以通过平面内旋转磁场来操纵。获得的结果可以考虑到磁环膜多物的出现。
We investigate a microscopic origin of nonreciprocal magnon that is distinct from the Dzyaloshinskii-Moriya interaction in a honeycomb antiferromagnet. The key ingredient is a symmetric anisotropic exchange interaction depending on the bond direction, which results in a valley-type nonreciprocal magnon excitations under the staggered antiferromagnetic ordering. Furthermore, we find this type of nonreciprocal magnon exhibits a peculiar magnetic-field response; the nonreciprocal direction can be manipulated by the in-plane rotating magnetic field. The obtained results can be accounted for the emergence of the magnetic toroidal multipoles.
