Theoretical analysis of the crossover temperature from over-the-barrier to quantum mechanical tunneling in multi-spin systems is presented and applied to the annihilation of a magnetic Skyrmions in a two-dimensional lattice. A remarkably strong dependence of the crossover temperature and the lifetime of the Skyrmions on the parameters in the extended Heisenberg Hamiltonian, i.e. the Dzyaloshinskii-Moriya interaction, out-of-plane anisotropy and applied magnetic field, is found and a region…

Quantum damping of skyrmion crystal eigenmodes due to spontaneous quasiparticle decay
The elementary excitations of skyrmion crystals experience both emergent magnetic fields and anharmonic interactions brought about by the topologically nontrivial noncollinear texture. The resulting

Quantum Dynamics of Skyrmions in Chiral Magnets
We study the quantum propagation of a Skyrmion in chiral magnetic insulators by generalizing the micromagnetic equations of motion to a finite-temperature path integral formalism, using field
Quantum collapse of a magnetic skyrmion
Large thermal fluctuations can destroy skyrmions - tiny speckles of rotated magnetization in two-dimensional films. Yet at low temperatures skyrmions are believed to be topologically stable, which
Paths to collapse for isolated skyrmions in few-monolayer ferromagnetic films
Magnetic skyrmions are topological spin configurations in materials with chiral Dzyaloshinskii-Moriya interaction (DMI), that are potentially useful for storing or processing information. To date,
Classical to quantum mechanical tunneling mechanism crossover in thermal transitions between magnetic states.
TLDR
Calculations of the jump rate and crossover temperature for tunneling are made for a molecular magnet containing an Mn4 group and are in excellent agreement with previously reported experimental measurements.
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.
Energy surface and lifetime of magnetic skyrmions
Stability of single skyrmionic bits
TLDR
It is shown by means of atomistic Monte Carlo simulations that the field-dependent mean lifetimes of the skyrmionic and ferromagnetic states have a high asymmetry with respect to the critical magnetic field, at which these lifetimes are identical.
Enhanced skyrmion stability due to exchange frustration
TLDR
This work shows that frustration of long range exchange interactions – a typical feature in itinerant electron magnets – is a route towards enhanced skyrmion stability even in systems with a ferromagnetic ground state.
