WebA simple differential set up for measuring changes in reflectivity of a flat surface of a ferromagnetic material, the so-called transverse magneto-optic Kerr effect, is described. The differential procedure is used with the aim of minimizing mechanical and optical noise. WebWe report a dramatic change in the intensity of a Raman mode with applied magnetic field, displaying a gigantic magneto-optical effect. Using the nonmagnetic layered material MoS 2 as a prototype system, we demonstrate that the application of a magnetic field perpendicular to the layers produces a dramatic change in intensity for the out-of-plane …

The magneto-optic Kerr effect relates light that is reflected from a magnetized surface and may change both polarization and reflected intensity. The magneto-optic Kerr effect is similar to the Faraday effect, which describes changes to light transmission through a magnetic material. In contrast, the … Meer weergeven In physics the magneto-optic Kerr effect (MOKE) or the surface magneto-optic Kerr effect (SMOKE) is one of the magneto-optic effects. It describes the changes to light reflected from a magnetized surface.
