In most studies utilizing the magneto-optic Kerr effect (MOKE), the detected change of polarized light upon reflection from a magnetized sample is supposed to be proportional to the magnetization M . However, MOKE signatures quadratic in M have also been identified and utilized, e.g., to sense the structural order in Heusler compounds, to detect spin-orbit torques or to image antiferro-magnetic domains. In our study, we observe a strong anisotropic MOKE contribution of third order in M in Ni(111…

The 2022 magneto-optics roadmap

Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or polarization upon reflection from or transmission through a magnetic sample, were discovered over a century and a



Investigation of Domains and Dynamics of Domain Walls by the Magneto‐optical Kerr‐effect

Kerr microscopy allows to image magnetic domains and magnetization processes in an optical polarization microscope. The method is based on the magneto-optical Kerr effect, that is, the rotation of
