Frustrated out-of-plane Dzyaloshinskii-Moriya interaction and the onset of atomic-scale 3 magnetic textures in 2D FeGeXTe (X = Te, Se, S) monolayers
Rabia Caglayan, Louise Desplat, Sergey Nikolaev +5
We theoretically study the effect of in- and out-of-plane Dzyaloshinskii-Moriya interaction (DMI) on the magnetic ground states of two-dimensional (2D) FeGeXTe (X=Te, Se, S) mo…
The 2026 Skyrmionics Roadmap
Sabri Koraltan, Claas Abert, Manfred Albrecht +64
Magnetic skyrmions and related topological spin textures have emerged as a central topic in condensed-matter physics, combining fundamental significance with potential for transfor…
Entropy-Assisted Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions
Lucile Soumah, Louise Desplat, Nhat-Tan Phan +7
We demonstrate a good agreement between mean dwell times measured in 50~nm diameter, perpendicularly magnetized superparamagnetic tunnel junctions (SMTJ), and theoretical predictio…
Observation of the sliding phason mode of the incommensurate magnetic texture in Fe/Ir(111)
Hung-Hsiang Yang, Louise Desplat, Volodymyr P. Kravchuk +6
The nanoscopic magnetic texture forming in a monolayer of iron on the (111) surface of iridium, Fe/Ir(111), is spatially modulated and uniaxially incommensurate with respect to the…
Eigenmodes of magnetic skyrmion lattices
Louise Desplat, Bertrand Dupé
We explore the interplay between topology and eigenmodes by changing the stabilizing mechanism of skyrmion lattices (skX). We focus on two prototypical ultrathin films hosting an h…
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…
