研究了理想单晶铁氧体内禀亚铁磁共振线宽的主要机制& Kasuya-LeCraw双磁振子-声子过程，考虑了局域磁离子对称性对磁振子-声子相互作用耦合强度的影响.结果表明，八面体对称位置对耦合没有贡献，而四面体和三角形对称位置对耦合有贡献。结果被用来估计的铁磁共振线宽YIG和钡铁氧体。>
The Kasuya-LeCraw two-magnon-one-phonon process, which is generally considered to be the primary mechanism responsible for the intrinsic ferrimagnetic resonance linewidth of perfect single crystal ferrites, is studied, taking into account the effects of the local magnetic ion symmetry on the magnon-phonon interaction coupling strength. It is shown that octahedral symmetry sites will not contribute to the coupling, but the tetrahedral and trigonal sites will. The results are used to estimate the FMR linewidth for both YIG and barium ferrite. >
