Fig. 1. (Color online) Temperature-dependent magnetic force microscopy (MFM) signal of curved wrinkles in the 2D Cr₂Ge₂Te₆ with (a) 1.3% strain and (b) 2.3% stain in experiment. Numerically calculated T_c and the magnetic anisotropy energy (MAE) as a function of strain for (c) monolayer and (d) bilayer Cr₂Ge₂Te₆, respectively. Adapted from Ref. [11].
