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 devices with the geometrically tunable parameters is proposed, namely, to filter elements.

Report

The paper "Curvature induced magnonic crystal in nanowires" by Anastasiia Korniienko et al develops the elegant idea of geometricalally induced effects in magnetism, particularly flexomagnetism, i.e. the symmetry breaking caused by bending of magnetic material. The authors argue that meander-shape wire should act as a magnonic crystal.
The paper conmprise essential and interesting physics, I have only minor remarks:
In the figure 3 caption there is a misprint: "ate" instead of "are"
In the page 9, bottom "where nu ( N" is irrelevant for the formula that do not contain any nu, it is better to place this explanation after the formula for deltaOmega in the next line.
