Extended Data Fig. 7: Quantitative comparison between experimental and theoretical images.
From: Skyrmion–antiskyrmion pair creation and annihilation in a cubic chiral magnet
a, Representative Lorentz TEM and phase shift images showing contrast features that correspond to a skyrmion, an antiskyrmion and a skyrmion-antiskyrmion pair. b, Lorentz TEM and phase shift images of a theoretically-simulated antiskyrmion. See simulation details in Fig. 1. From left to right: Under-, over-focus Lorentz TEM and electron phase shift images recorded using off-axis electron holography. c shows the corresponding magnetization vector field represented by isosurfaces mz = 0 of the antiskyrmion shown in b. d, Line plot profiles of the phase shift of the antiskyrmions shown in a and b at the positions marked by dashed lines. The experimental and theoretical phase shifts are in good agreement. The applied magnetic field in each case is 165 mT. The defocus distance is 600 μm. The images were recorded at a specimen temperature of 95 K.
