Description
Recently, centrosymmetric lanthanide metals have been the subject of intense research due to the discovery of skyrmions in materials such as Gd$_2$PdSi$_3$, GdRu$_2$Si$_2$, Gd$_3$Ru$_4$Al$_{12}$, EuAl$_4$, and EuNiGe$_3$. In this talk, I will present work on a europium triangle lattice compound in this family. Through spherical polarimetry using CRYOPAD at ThALES and polarized SANS measurements at D33, we demonstrate the existence of one single-q cycloidal and two multi-q vortex lattice states with unusually low symmetry propagation vectors. These unusual propagation vectors motivated the development of new SANS data visualization and analysis tools. I will also discuss how these states are deeply intertwined with the electronic structure of the material, and what insights this may provide for the design of new multi-q materials.
