Spatiotemporal steering of light using magnetic textures

We describe an archetypical approach for steering light using a combination of magneto-optical effects and the reconfigurability of magnetic domains in Yttrium-Iron Garnets thin films. The spontaneously formed stripe domains are used as a field-controlled optical grating, allowing an active spatiotemporal control of light. We discuss the basic ideas behind the approach and provide quantitative description of the field dependence of the obtained light patterns.
