摘要
Magneto-optical rotation was measured at room temperature for glasses containing Bi2O3–CdO–GeO2 (BCG), and Bi2O3–PbO–GeO2–B2O3 (BPGP). A pulsed magnetic field between 50 and 80 KG was used to measure Faraday rotation at 632.8 nm as a function of the concentration of Bi and Cd for BCG and Bi and Pb for BPGB. Verdet constant as high as 0.162 min G−1 cm−1 at 632.8 nm for the BPGB sample with the highest concentrations of Bi and Cd was found. Verdet constant increases linearly with the heavy-metal concentration for the BPGB whereas it reaches some saturation for the BCG system. Measurements of the magneto-optical rotation at other wavelengths in the visible and the refractive index at 632.8 nm are also reported.

在含有Bi 2 O 3·OO 2（BCG）的玻璃和Bi 2 O 3·B 2 O 3（BPGP） A脉冲的玻璃中，在室温下测量磁光旋转使用50和80KG之间的磁场来测量632μm处的法拉第旋转作为BCG的Bi和Cd的浓度的函数，并且用于BPGB的Bi和Pb的值为高达0分钟G sup鈭 对于具有最高浓度的Bi和Cd的BPGB样品，发现632℃下，对于BPGB的重金属浓度，Vetdet线性增加，而BCG达到一定饱和度系统中可见光的其他波长的磁光旋转和632 m的折射率的测量也被报告
