Magnon hybridization in easy-axis ferrimagnets

The controllable hybridization between right- and left-handed magnon modes is an important topic for utilizing the chiral degree of freedom in magnonics. It is commonly believed that the hybridization between different chiral magnon modes is a standard feature in the canted magnetic phase. This study discovers the presence of a magic ratio in canted ferrimagnets where the hybridization is extremely suppressed in both linear and nonlinear regimes. Combined with level-synchronization predictions, these results not only deepen the understanding of magnon mode hybridization in ferrimagnets, but also enrich the control methods for chiral magnons.
