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 theβ¦Β Expand

It is observed that the lifetime Ο of the skyrmions depends exponentially on temperature, Ο~Ο0 exp(ΞEkBT), and the prefactor Ο0 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.
