Composition-dependent Curie temperature of 8 nm Fe3+δ GeTe2. These Curie temperatures of different compositions were determined by Arrott-plots of transport data. With increasing the Fe composition, the Curie temperature increases. The negligible error bar for δ = 0 is 0.4 (Fe3GeTe2, Tc = 216.4 ± 0.4 K, shown in Fig. 2). The error bars were generated from the Arrott-plots fitting process
