Skyrmions are localized, topologically non-trivial spin structures which have raised high hopes for future spintronic applications. A key issue is skyrmion stability with respect to annihilation into the ferromagnetic state. Energy barriers for this collapse have been calculated taking only nearest neighbor exchange interactions into account. Here, we demonstrate that exchange frustration can greatly enhance skyrmion stability. We focus on the prototypical film system Pd/Fe/Ir(111) and use an… Expand
Skyrmion instabilities and distorted spiral states in a frustrated chiral magnet
Magnetic skyrmions are particlelike topological excitations that have recently generated much interest as candidates for future spintronic devices based on small skyrmion size, enhanced topologicalExpand

Universality of annihilation barriers of large magnetic skyrmions in chiral and frustrated magnets
Magnetic skyrmions are whirls in the magnetization whose topological winding number promises stability against thermal fluctuations and defects. They can only decay via singular spin configurations.Expand
Zero-field skyrmionic states and in-field edge-skyrmions induced by boundary tuning
When magnetic skyrmions are moved via currents, they do not strictly travel along the path of the current, instead their motion also gains a transverse component. This so-called skyrmion Hall effectExpand

Current-Induced Skyrmion Generation through Morphological Thermal Transitions in Chiral Ferromagnetic Heterostructures.
TLDR
It is demonstrated how by tuning the phase stability, one can reliably generate skyrmions by short current pulses and stabilize them at zero field, providing new means to create and manipulate spin textures in engineered chiral ferromagnets. Expand
Lifetime of racetrack skyrmions
TLDR
It is demonstrated that the racetrack skyrmion lifetime can be calculated from first principles as a function of temperature, magnetic field and track width, and this method combines harmonic transition state theory extended to include Goldstone modes, with an atomistic spin Hamiltonian parametrized from density functional theory calculations.

TLDR
It is demonstrated that sub-10 nm skyrmions are stabilized in these ferromagnetic Co films at zero field due to strong frustration of exchange interaction, together with Dzyaloshinskii–Moriya interaction and large magnetocrystalline anisotropy. Expand
