The evolution of chiral spin structures is studied in ferrimagnetTa/Ir/Fe/GdFeCo/Pt multilayers as a function of temperature using scanningelectron microscopy with polarization analysis (SEMPA). The GdFeCo ferrimagnetexhibits pure right-hand N\'eel-type domain wall (DW) spin textures over alarge temperature range. This indicates the presence of a negativeDzyaloshinskii-Moriya interaction (DMI) that can originate from both the topFe/Pt and the Co/Pt interfaces. From measurements of the DW width, as well ascomplementary magnetic characterization, the exchange stiffness as a functionof temperature is ascertained. The exchange stiffness is surprisingly mostlyconstant, which is explained by theoretical predictions. Beyond singleskyrmions, we find by direct imaging a pure N\'eel-type skyrmionium, which dueto the absence of a skyrmion Hall angle is a promising topological spinstructure to enable high impact potential applications in the next generationof spintronic devices.
