Inelastic neutron scattering in multi-Q structures in centrosymmetric systems — •Artem Nosenko and Dmitri Efremov — Leibniz Institute for Solid State and Materials Research, Dresden, Germany

In the current study we investigate centrosymmetric spin systems on a square lattice with spin frustration. We show that spin frustration leads to several single-Q helical structures and a double-Q structure.

We study the magnon spectra and calculate the dynamical structure factor for these magnetic structures. The results obtained show that inelastic neutron scattering can be a perfect tool for the identification of double-Q structures.

Keywords: Multi-Q structures; Magnon calculations
