【Abstract】 Based on the Faraday effect,an experimental light spectrometer was setup under low magnetic field and room temperature and the relationship between the wavelength of incident light and Faraday rotation angle was investigated.The Verdet constants of MR3-2crystal sample under different wavelengths of incident light were obtained from the experiments.Furthermore,the relationship between Verdet constant and incident light wavelength was established by fitting analysis,and the experimental curves were agreed well with the theoretical results.更多还原
