本文用振动理论和经典电磁场论,分析论证了发生磁效应的机理。求得费尔德(Verdet)常数与入射光波长的函数关系。 用He-Ne激光6328(?)和干涉滤波片,对镧(Le)玻璃、重火石(ZF)玻璃以及铽(Tb)玻璃三种材料进行了磁光效应的测定。得到费尔德常数的实验值。根据实验数据,用计算法、作图法可确定出有关方程的系数,从而得到磁光效应随入射光波长不同的变化规律和磁光效应随温度的变化规律。
In this paper, the vibration theory and the classical electromagnetic field theory, analysis and demonstration of the magnetic effect of the mechanism. Obtain the Verdet constant as a function of incident light wavelength. The magneto-optical effect was measured on He-Ne laser 6328 (?) And interference filter for lanthanum (Le) glass, pyrotechnic (ZF) glass and terbium (Tb) glass. Obtain the experimental values of the Verdet constant. According to the experimental data, the coefficients of the equation can be determined by the calculation method and the plot method, and the variation law of the magneto-optical effect with the wavelength of the incident light and the variation law of the magneto-optical effect with temperature are obtained.
