Curvature induced magnonic crystal in nanowires
arXiv:1905.07795 · doi:10.21468/SciPostPhys.7.3.035
Abstract
A new type of magnonic crystals, curvature induced ones, is realized in ferromagnetic nanowires with periodically deformed shape. A magnon band structure of such crystal is fully determined by its curvature: the developed theory is well confirmed by simulations. An application to nanoscale spintronic devises with the geometrically tunable parameters is proposed, namely, to filter elements.
