Magneto-optic kerr microscope
WebMar 8, 2016 · One arrangement is most suitable for MO Kerr effect (MOKE) microscopy of large samples with an in-plane alignment of magnetization. The other kind of setup is an adapted polarized light microscope and is suited for MO effect domain observations with high magnification and high spatial resolution. WebKerr rotation is a rotation in the plane of polarization of transmitted light, and Kerr ellipticity is the ratio of the major to minor axis of the ellipse traced out by elliptically polarized light on the plane through which it propagates. Changes in the orientation of polarized incident light can be quantified using these two properties.
