WebFeb 1, 2016 · The magneto-optical Kerr effect (MOKE) is a widely used technique in magnetic domain imaging for its high surface sensitivity and external magnetic compatibility. In this work, we use the generalized magneto-optical ellipsometry technique to study the influence of polarizer and analyzer azimuth on domain image contrast in the Kerr … WebMicroscopy. A Kerr microscope relies on the MOKE in order to image differences in the magnetization on a surface of magnetic material. In a Kerr microscope, the illuminating light is first passed through a polarizer filter, then reflects from the sample and passes through an analyzer polarizing filter, before going through a regular optical microscope. sail hard mechanical properties
