Magneto-Optical Kerr Microscope (MOKE) - ETH Zurich

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. WebKerr Microscope system is facility for the visualisation of magnetic domains and magnetization processes as well as for optically recording magnetization curves on all kinds of magnetic materials, including bulk specimens like sheets or ribbons, magnetic films and multilayers, patterned films or micro- and nanowires. forest of trees japan https://ecolindo.net
