Direct observation of attractive skyrmions and skyrmion clusters in the cubic helimagnet Cu2OSeO3

Autor: Loudon, JC, Leonov, AO, Bogdanov, AN, Hatnean, MC, Balakrishnan, G

We report the discovery of attractive magnetic skyrmions and their clusters in non-centrosymmetric ferromagnets. These three-dimensional solitons have been predicted to exist in the cone phase of chiral ferromagnets (J. Phys: Condens. Matter 28 (2016
