Stabilization of skyrmion textures by uniaxial distortions in noncentrosymmetric cubic helimagnets

A. B. Butenko, A. A. Leonov, U. K. Rößler, and A. N. Bogdanov
In cubic noncentrosymmetric ferromagnets, uniaxial distortions suppress the helical states and stabilize skyrmion lattices in a broad range of thermodynamical parameters. Using a phenomenological theory for modulated and localized states in chiral magnets, the equilibrium parameters of the...

Influence of the Dzyaloshinskii-Moriya interaction on vortex states in magnetic nanodisks

A. B. Butenko, A. A. Leonov, A. N. Bogdanov and U. K. Rößler
Curling magnetic vortices with chiral rotation sense and polarity of the core magnetization can exist in magnetic circular nanostructures. Broken mirror symmetry at surfaces/interfaces of magnetic nanostructures induces chiral Dzyaloshinskii-Moriya interactions which may strongly affect the...

Theory of vortex states in magnetic nanodisks with induced Dzyaloshinskii-Moriya interactions

A. B. Butenko, A. A. Leonov, A. N. Bogdanov, and U. K. Rößler
Broken inversion symmetry in magnetic nanostructures induces Dzyaloshinskii-Moriya couplings. In the presence of surfaces/interfaces the magnetism of magnetic nanodisks can be essentially affected by these chiral couplings. Within a micromagnetic approach we calculate the equilibrium sizes and...
