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…

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.

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.
