Curvature induced magnonic crystal in nanowires (1905.07795v4)
Published 19 May 2019 in cond-mat.mes-hall
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.
