DFT analysis of GdRu2X2 (X = Si, Ge, Sn) links increased destabilizing band energy and competing exchange interactions to easier skyrmion formation, predicting GdRu2Sn2 as a high-temperature, low-field skyrmion host.
Similar spin density features are observed in the [110] projection (Figure S5), connecting to the QA = (q, q, 0) FSN vector in GdRu 2X2
