The properties of nanocomposite (BiDy)3(FeGa)5O12:Bi2O3 magneto-optic garnet films for applications in nanophotonics, ultrafast switching and integrated optoelectronics

We investigate the properties and applications of newly-developed RF-sputtered nano-composites with record-high magneto-optic quality (exceeding 25° at 532 nm and 42° at 635 nm). Bi-substituted dysprosium-gallium iron garnet layers with excess co-sputtered bismuth oxide content are demonstrated to possess very attractive optical and magnetic properties, which makes them suitable for novel magneto-optic and nanophotonic applications.
