GdRu2Si2 is a centrosymmetric magnet in which a skyrmion lattice has recently been discovered. Here, we investigate the magnetic structure of the zero-field ground state using neutron diffraction on single crystal and polycrystalline 160GdRu2Si2. In addition to observing the principal propagation vectors q1 and q2, we discover higher-order magnetic satellites, notably q1+2q2. The appearance of these satellites is explained within the framework of a double-Q constant-moment solution. Using powder diffraction, we implement a quantitative refinement of this model. This structure, which contains vortexlike motifs, is shown to have a one-dimensional topological charge density. |
