基于Safonov和Yamazaki所发展的激励自旋波非线性辐射衰减的理论 [J .MMM .16 1(1996 ) 2 75 ],考虑磁激子与磁激子以及磁激子与光子的两种非线性相互作用过程 ,计算了微波谐振腔Q值对磁激子振幅不稳定态阈值的影响 ,结果与实验数据基本一致
Based on the theory developed by Safonov and Yamazaki for the non-linear radiative decay of excitation spin-waves [J .MMM. 161 (1996) 2 75], we consider two kinds of nonlinearities of magnetic excitons and magnetic excitons and magnetic excitons and photons Interaction process, the influence of the Q value of the microwave resonator on the threshold value of the amplitude of the magnetic exciton is calculated and the results are basically consistent with the experimental data
