Skyrmionic textures in chiral magnets
U. K. Rößler, A. A. Leonov, A. N. Bogdanov
In non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya exchange stabilizes Skyrmion-strings as excitations which may condense into multiply modulated phases. Such extended…
Stabilization of Skyrmion textures by uniaxial distortions in noncentrosymmetric cubic helimagnets
A. B. Butenko, A. A. Leonov, U. K. Rößler +1
In cubic noncentrosymmetric ferromagnets uniaxial distortions suppress the helical states and stabilize Skyrmion lattices in a broad range of thermodynamical parameters. Using a ph…
Spontaneous Skyrmion Ground States in Magnetic Metals
U. K. Roessler, A. N. Bogdanov, C. Pfleiderer
Since the 1950s Heisenberg and others have attempted to explain the appearance of countable particles in quantum field theory in terms of stable localized field configurations. As…
Effect of weak disorder on the ground state of uniaxial dipolar spin systems in the upper critical dimension
A. V. Klopper, U. K. Roessler, R. L. Stamps
Extensive Monte Carlo simulations are used to investigate the stability of the ferromagnetic ground state in three-dimensional systems of Ising dipoles with added quenched disorder…
