PROBLEM TO BE SOLVED: To shorten a time required for measuring wavelength dependence of an angle change of a plane of polarization in a material.;SOLUTION: A magneto-optical effect measuring device 10 comprises: a white light source 1 for generating white light; a polarizer 2 for forming linearly polarized light from the white light and making the linearly polarized light incident on a sample S; an electromagnet for applying a magnetic field to the sample S; an analyzer 5 on which detection light emitted from the sample S is made incident; a spectrometer 7 on which a passed light passed through the analyzer 5 is made incident; an optical sensor 8 for detecting respective light intensities of wavelength components with different wavelengths obtained by splitting light by the spectrometer 7; and an arithmetic unit 9 for calculating wavelength dependence of magneto-optical characteristics of the sample S from respective light intensities of the detected wavelength components.;COPYRIGHT: (C)2013,JPO&INPIT
