Skyrmionic textures in chiral magnets

Abstract

In non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya exchange stabilizes Skyrmionstrings as excitations which may condense into multiply modulated phases. Such extended Skyrmionic textures are determined by the stability of the localized ”solitonic ” Skyrmion cores and their geometrical incompatibility which frustrates regular space-filling. We present numerically exact solutions for Skyrmion lattices and formulate basic properties of the Skyrmionic states. PACS numbers: 75.30.Kz 75.10.-b 75.70.-i, 1 I.
