Understanding, controlling and, more importantly, enhancing the interaction between light
(photons) and spin waves (magnons) can be, among others, a step towards the realization
of magnon-mediated microwave-to-optical transducers for quantum computing applications
or hybrid solid-state spintronic-photonic interconnections. In this respect, the development of
novel composite multifunctional micro/nanostructures—so-called optomagnonic—which
simultaneously control optical and spin waves and enhance their interaction, is particularly …
