Figure 1
Displacement fields around a dislocation. (a) Fresnel image of a 5–7 dislocation in a skyrmion lattice recorded at 230 K in a lamella of FeGe with a defocus of 800 \(\upmu \hbox {m}\) and in the presence of an external magnetic field of 145 mT. (b) Magnified image of the dislocation. (c,d) Experimental horizontal and vertical components of the displacement field (\(u_{x}\),\(u_{y}\)) calculated from (a) using GPA. Contours every 5 nm between − 50 and + 50 nm. (e,f) Theoretical components of the displacement field calculated from linear elastic theory.
