Field tunable three-dimensional magnetic nanotextures in cobalt-nickel nanowires
I. M. Andersen, D. Wolf, L. A. Rodriguez +8
Cylindrical magnetic nanowires with large transversal magnetocrystalline anisotropy have been shown to sustain non-trivial magnetic configurations resulting from the interplay of s…
Theory of skyrmion states in liquid crystals: axisymmetric cholesteric bubbles (spherulites)
A. O. Leonov, I. E. Dragunov, U. K. Rößler +1
Within the Oseen-Frank theory we derive numerically exact solutions for axisymmetric localized states in chiral liquid crystal layers with homeotropic anchoring. These solutions de…
Target-skyrmions and skyrmion clusters in nanowires of chiral magnets
A. O. Leonov, U. K. Rößler, M. Mostovoy
In bulk non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya exchange stabilizes tubular skyrmions with a reversed magnetization in their centers. While the double-twist is…
Discrete helicoidal states in chiral magnetic thin films
M. N. Wilson, E. A. Karhu, D. P. Lake +4
Magnetometry and magnetoresistance measurements in MnSi thin films and rigorous analytical solutions of the micromagnetic equations show that the field-induced unwinding of confine…
Chiral skyrmions in thin magnetic films: new objects for magnetic storage technologies?
N. S. Kiselev, A. N. Bogdanov, R. Schäfer +1
Axisymmetric magnetic lines of nanometer sizes (chiral vortices or skyrmions) have been predicted to exist in a large group of noncentrosymmetric crystals more than two decades ago…
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…
