Paper Abstract

A simple technique of measuring the polar magneto-optical Kerr effect using a rotating analyzer is developed. The technique of the rotating analyzer ellipsometer is adopted for the measurement of polarization state of light. The light intensities are digitized automatically by the simple system consisted of an analog-to-digital converter and a micro-encoder and then Fourier transformed. The expressions of rotation angle (theta) and ellipticity angle (epsilon) are obtained in terms of the Fourier coefficients of the light intensity versus rotating analyzer. This technique is applied to (theta) and (epsilon) measurement of Co/Pt films. The precision of 0.01 degree(s) in angle measurement is verified.
