A method is described for measuring the amplitude and phase of the complex Kerr magnetooptic coefficients. A magnetic metal surface to be measured is switched between its magnetic states at an ac rate, thereby modulating a reflected light beam. By measuring the modulation depth with a synchronous detector and one angle, the two quantities above are determined. The method requires no precision optical equipment as is needed with polarimetric techniques.
