Direct Observation of Attractive Skyrmions and Skyrmion Clusters in the Cubic Helimagnet CuOSeO
J. C. Loudon, A. O. Leonov, A. N. Bogdanov +2
We report the discovery of attractive magnetic skyrmions and their clusters in non-centrosymmetric ferromagnets. These three-dimensional solitons have been predicted to exist in th…
Internal structure of hexagonal skyrmion lattices in cubic helimagnets
D. McGrouther, R. J. Lamb, M. Krajnak +6
We have utilised a high spatial resolution imaging method, Differential Phase Contrast (DPC) performed in a scanning transmission electron microscope (STEM), for precise measuremen…
Three-dimensional chiral skyrmions with attractive interparticle interactions
A. O. Leonov, T. L. Monchesky, J. C. Loudon +1
We introduce a new class of isolated three-dimensional skyrmion that can occur within the cone phase of chiral magnetic materials. These novel solitonic states consist of an axisym…
Confinement of Chiral Magnetic Modulations in the Precursor Region of FeGe
H. Wilhelm, M. Baenitz, M. Schmidt +5
We report on magnetic susceptibility and specific heat measurements of the cubic helimagnet FeGe in external magnetic fields and temperatures near the onset of long-range magnetic…
Confinement of Skyrmion states in noncentrosymmetric magnets
A. A. Leonov, A. N. Bogdanov, U. K. Roessler
Skyrmionic states in noncentrosymmetric magnets with Lifshitz invariants are investigated within the phenomenological Dzyaloshinskii model. The interaction between the chiral Skyrm…
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…
Theory of vortex states in magnetic nanodisks with induced Dzyaloshinskii-Moriya interactions
A. B. Butenko, A. A. Leonov, A. N. Bogdanov +1
Vortex states in magnetic nanodisks are essentially affected by surface/interface induced Dzyaloshinskii-Moriya interactions. Within a micromagnetic approach we calculate the equil…
Phenomenological theory of magnetization reversal in nanosystems with competing anisotropies
A. A. Leonov, U. K. Roessler, A. N. Bogdanov
The interplay between intrinsic and surface/interface-induced magnetic anisotropies strongly in- fluences magnetization processes in nanomagnetic systems. We develop a micromagneti…
