Magneto-optical light modulator with local domain wall manipulation

We consider a scheme of Faraday magneto-optical light modulator with local magnetization control via magneto-electric effect. Our earlier researches of bismuth-substituted iron garnets films showed the giant domain wall (DW) displacement in electric field of charged tip due to magneto-electric effect [1, 2]. The displacement gives the opportunity to the local magnetization switching on the spatial scales about few microns.
