Enhanced skyrmion stability due to exchange frustration

HIGHLIGHTS

  • who: Corrected Author Correction et al. from the (UNIVERSITY) have published the paper: Enhanced skyrmion stability due to exchange frustration, in the Journal: (JOURNAL) of 11/09/2017
  • what: The authors demonstrate that exchange frustration can greatly enhance skyrmion stability. The authors focus on the prototypical film system Pd/Fe/Ir(111) and use an atomistic spin model parametrized from first-principles calculations. The authors show that energy barriers and critical fields of skyrmion collapse as well as skyrmion lifetimes are drastically enhanced due to frustrated exchange and that antiskyrmions are metastable. The work shows . . .
