Garst A magnetic helix realizes a one-dimensional magnetic crystal with a period given by the pitch length λ h . Its spin-wave excitations—the helimagnons—experience Bragg scattering off this periodicity, leading to gaps in the spectrum that inhibit their propagation along the pitch direction. Using high-re… [Phys. Rev. Lett. 115, 097203] Published Fri Aug 28, 2015
