Topological protection precludes a continuous deformation between topologically inequivalent configurations in a continuum. Motivated by this concept, magnetic skyrmions, topologically nontrivial spin textures, are expected to exhibit the topological stability, thereby offering a prospect as a nanometer-scale non-volatile information carrier. In real materials, however, atomic spins are configured as not continuous but discrete distribution, which raises a fundamental question if the… Expand

Magnetic stripes and skyrmions with helicity reversals
Surprisingly, it is found that the magnetic bubbles and stripes in the hexaferrite have a much more complex structure than the skyrmions and spirals in helimagnets, which are associated with the new degree of freedom—helicity (or vector spin chirality) describing the direction of spin rotation across the domain walls.

Tailoring the topology of an artificial magnetic skyrmion.
E epitaxial magnetic thin films are reported, in which an artificial skyrmion is created by embedding a magnetic vortex into an out-of-plane aligned spin environment and shows distinct annihilation behaviour of the skyrnion core for the two different skyrMion states, suggesting a topological effect of the magnetic skyr mions in the core annihilation process.

Entropy-limited topological protection of skyrmions
It is observed that the lifetime τ of the skyrmions depends exponentially on temperature, τ~τ0 exp(ΔEkBT), and the prefactor τ0 of this Arrhenius law changes by more than 30 orders of magnitude for small changes of the magnetic field, reflecting a substantial reduction of the lifetime of skyrnions by entropic effects and, thus, an extreme case of enthalpy-entropy compensation.
