Abstract

Recent discoveries of multi-\textbf{Q} magnetic structures in centrosymmetric compounds have stimulated growing interest in their microscopic origin and observable properties. Here, we calculate the dynamical magnetic structure factor for a double-\textbf{Q} magnetic structure and compare it with that of a single-\textbf{Q} configuration.
