Dzyaloshinskii-Moriya interaction induced by an ultrashort electromagnetic pulse: Application to coherent (anti)ferromagnetic skyrmion nucleation
L. Desplat, S. Meyer, J. Bouaziz +4
We show how a Dzyaloshinskii-Moriya interaction can be generated in an ultrathin metal film from the induced internal electric field created by an ultrashort electromagnetic pulse.…
Quantifying the thermal stability in perpendicularly magnetized ferromagnetic nanodisks with forward flux sampling
L. Desplat, J. -V. Kim
The thermal stability in nanostructured magnetic systems is an important issue for applications in information storage. From a theoretical and simulation perspective, an accurate p…
Entropy-reduced retention times in magnetic memory elements: A case of the Meyer-Neldel Compensation Rule
L. Desplat, J. -V. Kim
We compute mean waiting times between thermally-activated magnetization reversals in a nanodisk with parameters similar to a free CoFeB layer used in magnetic random access memorie…
Asymmetric skyrmion-antiskyrmion production in ultrathin ferromagnetic films
Ulrike Ritzmann, Louise Desplat, Bertrand Dupé +2
Ultrathin ferromagnets with frustrated exchange and the Dzyaloshinskii-Moriya interaction can support topological solitons such as skyrmions and antiskyrmions, which are metastable…
Path sampling for lifetimes of metastable magnetic skyrmions and direct comparison with Kramers' method
L. Desplat, C. Vogler, J. -V. Kim +2
We perform a direct comparison between Kramers' method in many dimensions -- i.e., Langer's theory -- adapted to magnetic spin systems, and a path sampling method in the form of fo…
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…
