Design and Construction of the Magneto-Optical Kerr Effect Microscope
Xue Han, Mentors Ania Jayich and Alec Jenkins (Physics)

Magneto-Optical Kerr Effect (MOKE) describes the changes to the polarization of light reflected from a magnetic surface. Based on MOKE, the Magneto-Optical Kerr Effect Microscope investigates ferromagnetic materials by imaging their magnetic domains due to changes in polarization of light in different magnetization orientations. Such microscopy has gained more attention recently since it not only enables instant wide-field material imaging, but also offers spin dynamics visualization. In this research, I design and construct a polar MOKE microscope, which would be sensitive to out of plane magnetization vectors only. The MOKE microscope will be used in visualizing skyrmions, which are nano-scaled perturbations to a magnet.
