Kort presentation

There are many optical components, such as lenses or wave plates, that owe their effects to the gradual changes in the amplitude, propagation direction, and phase of the light that accumulate as the light propagates through materials over distances much larger than its wavelength. Would it not be incredible if one could replicate the effects by using a material that is just a few nanometers thick? Magnetoplasmonic nanostructures can make this possible.

The interactions of light and matter follow some pretty basic principles. If an electron is sensing the electric field of a photon it will be stimulated accordingly and this describes the absorption and light scattering properties of a material. Magneto-plasmonics is all about creating magnetic nanostructures to have active control of these properties and to create materials with completely new properties. 
What we are aiming at is to control effects such as birefringence and dichroism (appearing as magneto-optic Kerr rotation and ellipticity) with external magnetic fields and we do this with periodic ferromagnetic nanostructures. We are looking at grating coupled surface plasmons and polaritons with far field measurements such as angle and energy resolved transverse MOKE, specular reflectivity and transmission.
