Ab initio analysis of magnetic properties of prototype B20 chiral magnet FeGe

30 Sep 2019 Grytsiuk S. Hoffmann M. Hanke J. -P. Mavropoulos P. Mokrousov Y. Bihlmayer G. Blügel S.

FeGe in the B20 phase is an experimentally well-studied prototypical chiral magnet exhibiting helical spirals, skyrmion lattices and individual skyrmions with a robust length of 70~nm. While the helical spiral ground state can be verified by first-principles calculations based on density functional theory, this feature size could not be reproduced even approximately... (read more)
