Paths to annihilation of first and second-order (anti)skyrmions via (anti)meron nucleation on the frustrated square lattice
L. Desplat, J. -V. Kim, R. L. Stamps
We study annihilation mechanisms of small first- and second-order skyrmions and antiskyrmions on the frustrated square lattice with broken inversion symmetry (DMI). W…

Thermal stability of metastable magnetic skyrmions: Entropic narrowing and significance of internal eigenmodes
L. Desplat, D. Suess, J-V. Kim +1
We compute annihilation rates of metastable magnetic skyrmions using a form of Langer's theory in the intermediate-to-high damping (IHD) regime. For a Néel skyrmion, a Bloch skyrmi…
