Abstract
Magnonics is now an attractive field which focuses on the dynamic characteristics of magnons, a kind of quasiparticles in magnetic media, and attempts to apply magnons for functional devices. In order to construct magnon-based devices, it is necessary to fabricate materials with specific and tunable magnon bands and bandgaps. Skyrmion-based magnonic crystal is one of the most suitable materials which possess periodical skyrmion structure and show applicative magnon bands and bandgaps. In this review, we provide an overview over recent theoretical and experimental research on skyrmion-based magnonic crystals. We will first provide an introduction of magnonic crystals and magnetic skyrmion. Then, we will show the theoretical and experimental progress on skyrmion-based magnonic crystals and their magnon band characteristics. At the end, we will give an outlook and perspectives of new fascinating fields on topological nontrivial magnon modes, as well as hybrid and quantum magnonic phenomena of skyrmion-based magnonic crystals.
