Chiral Tubular Magnonic Crystals with Periodic Dzyaloshinskii--Moriya Interaction
P. Contreras-Gallardo, J. Flores-Farias, B. Mimica-Figari +3
We introduce a chiral tubular magnonic crystal formed by a ferromagnetic nanotube with a periodically modulated interfacial Dzyaloshinskii--Moriya interaction (DMI). Using a plane-…

Dzyaloshinskii-Moriya Interaction and Dipole-Exchange Curvature Effects on the Spin-Wave Spectra of Magnetic Nanotubes
B. Mimica-Figari, P. Landeros, R. A. Gallardo
This work explores spin-wave dynamics in magnetic nanotubes, focusing on the influence of the Dzyaloshinskii-Moriya interaction and curvature. The study uses analytical methods to…

Toroidal Moments in Confined Nanomagnets and their Impact on Magnonics
Felipe Brevis, Lukas Körber, B. Mimica-Figari +3
The nonreciprocity created by dipolar coupling, electric currents, and Dzyaloshinskii-Moriya interactions is discussed in cases where the magnon propagation direction has a compone…
