Abstract

Read online

Domain wall skyrmions have been proposed but the experimental observation has been difficult. Here, the authors report experimental discovery of domain wall bimerons due to the interplay between magnetic anisotropy and Dzyaloshinskii-Moriya interaction in chiral magnet Co-ZnMn(110) thin films.
