Fig. 5: Thickness-dependent evolution of Néel-type textures in a thin lamella of Cr1+δTe2 as a function of magnetic field at 100 K.
From: Observation of Néel-type skyrmions in acentric self-intercalated Cr1+δTe2
a, b Lorentz transmission electron microscopy image of Néel-type textures recorded at different magnetic fields for α = +6° for lamella thicknesses of a ≈ 75 nm (Region I) and b ≈ 162 nm (Region II). These images are acquired at a defocus value of −1.5 mm. c Skyrmion diameter (dsk) versus magnetic field (H) for Regions I and II. d Skyrmion diameter (dsk) versus temperature (T) for Regions I and II. The dark lines correspond to bending contours. The error bars in c, d represent the standard deviation in the skyrmion diameter.
