Extended saddle points govern long-lived antiskyrmions
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Achieving long-lived nanoscale magnetic solitons remains a central challenge, as their lifetimes typically decrease rapidly with temperature. Here, we demonstrate that anisotropic…

A new skyrmion topological transition driven by higher-order exchange interactions in Janus MnSeTe
Megha Arya, Moritz A. Goerzen, Lionel Calmels +4
Two-dimensional (2D) van der Waals magnets offer a promising platform for pushing skyrmion technology to the single-layer limit with high tunability. While Dzyaloshinskii-Moriya in…
