Finite-temperature phase transitions across spin symmetries in two-dimensional magnets
Chen Chen, Moritz A. Goerzen, Megha Arya +3
Recent advances in intrinsic two-dimensional (2D) magnets have created a need for a unified understanding of finite-temperature phase transitions across different spin-symmetry cla…
Interaction between point defects and vertical inversion domain walls in wurtzite AlN
Loris Naudin, Charles Paillard, Laurent Bellaiche +2
Alloyed aluminium nitride compounds constitute a promising class of ferroelectric materials due to their high remanent electric polarizations, large band gaps and structural compat…
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…
