Author Correction: Enhanced skyrmion stability due to exchange frustration

Correction to: Scientific Reports 10.1038/s41598-017-12525-x, published online 26 September 2017

In Figure 2, the data points for the skyrmion and antiskyrmion radii (fcc J_DFT, fcc J_eff, hcp J_DFT, hcp J_eff and ASk) were incorrect. Additionally, the legend of Figure 2,

“Skyrmion radius vs. magnetic field. Radii of skyrmions in Pd/Fe/Ir(111) obtained for different parameter sets as a function of the applied magnetic field. As a reference, the radii obtained experimentally by Romming et al.²⁴ are shown as green triangles. Note that we have obtained the skyrmion radii for the experimentally available field strengths by applying our definition of the skyrmion radius to the skyrmion profiles shown in Fig. 3(a) of ref.²⁴. Antiskyrmions (ASk) were only metastable for fcc-Pd/Fe/Ir(111) with DFT parameters.”

should read:

“Skyrmion radius vs. magnetic field. Radii of skyrmions in Pd/Fe/Ir(111) obtained for different parameter sets as a function of the applied magnetic field. As a reference, the radii obtained experimentally by Romming et al.²⁴ are shown as green triangles. Note that we have obtained the skyrmion radii for the experimentally available field strengths by applying our definition of the skyrmion radius to the skyrmion profiles shown in Fig. 3(a) of ref.²⁴. Antiskyrmions (ASk) were only metastable for fcc-Pd/Fe/Ir(111) with DFT parameters. Note that the radii obtained from experiments are very close to those from J_DFT for hcp stacking of Pd.”

The correct Figure 2 and its accompanying legend appear below as Figure 1. Note that the skyrmion profiles in the insets are the same as the profiles in Figure 2 of the original paper.
