When an electron moves in a smoothly varying non-collinear magnetic structure, its spin orientation adapts constantly, thereby inducing forces that act both on the magnetic structure and on the electron. These forces may be described by electric and magnetic fields of an emergent electrodynamics1, 2, 3, 4. The topologically quantized winding number of so-called skyrmions—a type of magnetic whirl discovered recently in chiral magnets5, 6, 7—has been predicted to induce exactly one quantum of… Expand

TLDR
It is argued that multiferroic skyrmions show unique coupled oscillation modes of magnetizations and polarizations, so-called electromagnon excitations, which are both magnetically and electrically active, and interference between the electric and magnetic activation processes leads to peculiar magnetoelectric effects in a microwave frequency regime. Expand
Theory of current-driven skyrmions in disordered magnets
TLDR
It is revealed by a numerical simulation of Landau-Lifshitz-Gilbert equation that there are four different skyrmion phases with the strong disorder, and the microscopic mechanisms of the new phases (C) and (D) are analyzed theoretically, which offer a coherent understanding of the skyrnion dynamics under current with disorder.

Magnetic skyrmions in chiral magnets are two-dimensionally localized and topologically protected vortex-like magnetic textures with particle-like properties. They are currently under intense scrutinyExpand
Current-induced dynamics of skyrmion strings
TLDR
It is shown in the chiral magnet MnSi that the current-induced deformation dynamics of skyrmion strings results in transport response associated with the real-space Berry phase, revealing the dynamical nature of string-like objects and consequent transport outcomes in noncentrosymmetric systems.

Magnetoelectric effect and orbital magnetization in skyrmion crystals: Detection and characterization of skyrmions

Diameter-independent skyrmion Hall angle observed in chiral magnetic multilayers
TLDR
The authors show that in contrast to predictions the skyrmion Hall angle is independent of their diameter and motion is dominated by disorder and skyrMion-skyrmions interactions in the system. Expand

Dynamics of skyrmion in disordered chiral magnet of thin film form
TLDR
This work studies theoretically the current-driven dynamics of a skyrmion string under disorder potential by systematically changing the thickness of the sample to reveal the dynamical phase diagram in the plane of current density and thickness, indicating that there is the optimal range of thickness for the topological stability of skyrnion string enhanced compared with a two-dimensional skyrMion.

Chirality-driven orbital magnetic moments as a new probe for topological magnetic structures
TLDR
The orbital magnetism of skyrmions is studied and it is demonstrated that the contribution driven by the emergent magnetic field is topological, which means that the topological contribution to the orbital moment does not change under continuous deformations of the magnetic structure. Expand
