While, for semiconductors photoexcited by a circularly polarized pump, the polarization plane of a linearly polarized probe has been shown to rotate, we here predict a spectacular change when the pump beam is linearly polarized, from…

It is generally believed that the magneto-optical Faraday effect appears in the the bulk of a magnetic material and its sign is fully determined by the sign of the non-diagonal permittivity element. Here we reveal an additional contribution…

We investigate the non-resonant all-optical switching of magnetization. We treat the inverse Faraday effect (IFE) theoretically in terms of the spin-selective optical Stark effect for linearly or circularly polarized light. In the dilute…
