The experimental demonstration of a novel integrated optical isolator concept is presented. By using a transversely magnetized ferromagnetic metal as the electric contact of an active waveguide structure, the transverse magneto-optic Kerr effect induces nonreciprocal loss of the TM guided mode. Based on this principle we designed, fabricated and characterized the first version of an optical iso...

The nonlinear magneto-optical Kerr-effect (NOLIMOKE) is determined for freestanding Fe monolayers with several in-plane structures from first principles. Based on the theory of nonlinear magneto-optics by Hübner and Benne-mann [Phys. Rev. B, 40, 5973 (1989)] we calculate the nonlinear susceptibil-ities of the monolayers using the ab initio FLAPW-method WIEN95 with the additional implementation ...

First-principles electronic structure studies based on local spin density functional theory and performed on extremely complex simulations of ever increasingly realistic systems, play a very important role in explaining and predicting surface and interface magnetism. This review deals with what is a major issue for "rst-principles theory, namely the theoretical/computational treatment of the we...

A significant interest in combining plasmonics and magnetism at the nanoscale gains momentum in both photonics and magnetism sectors that are concerned with the resonant enhancement of light-magnetic-matter interaction in nanostructures. These efforts result in a considerable amount of literature, which is difficult to collect and digest in limited time. Furthermore, there is insufficient excha...

Diffracted magneto optical Kerr effect (DMOKE) is a widely used technique for investigating magnetization distributions and reversal processes in periodic arrays of micron and submicron magnetic elements [1]. In most cases, the magnetic arrays are made of isolated magnetic entities where the magnetic interaction between them is limited to magnetic dipolar interactions. Little is known about wha...
