On the existence, structure, and stability of chiral ,

This main focus of this thesis is on the existence and stability of topological solitons called chiral magenetic skyrmions, arising in planar ferromagnets including combinations of Zeeman, anisotropy, and chiral Dzyoloshinskii-Moriya interactions The first part deals with the existence of skyrmions with co-rotational symmetry under small chiral interaction, which is a variational ,...
