Abstract

Here we report on the magneto-optical Kerr eect (MOKE) employing a nematic liquid crystal (LC) device as optical modulator. This device allows performing intensity, phase and polarization modulated measurements with huge signal to noise ratio if compared to those obtained by mean of an opto-mechanical chopper and a photo-elastic modulator (PEM). The results demonstrate that the optimal performance is achieved modulating the polarization state of the incident light by means of the LCs.
