摘要
继作者对Damon和Easbach(简称DE)理论在长波部分的修正,本文探讨了DE理论在短波部分的适应性,研究了具有单轴各向异性和弱交换作用的偶极自旋模式,给出了临界角的表达式,并分析了频率-波矢空间的实际图象。所得结果与铁磁共振的频谱实验结果较好地符合。
This paper presents an investigation of dipole spin modes in an anisotropic medium with uniaxial anisotropy and a weak exchange effect. The critical angle between surface wave and volume wave is given according to the new circumstance and the real ω vs k figure in space is analysed. The experimental results of single crystal YIG FMR spectra agree well with our calculation.
