| Abstract: | The experimental apparatus for measuring the peak value of the Faraday rotation F induced by alternating magnetic field is set up. The sample used here is a magneto-optical film Prefared by liquid Phase epitaxy. By measuring the fundamental and the second harmonic of the photodetector current at a angle away from cross setting of P, A, the F can be calculated. The method is simple and accurate and can be used at any frequency. |
