Quantum rescaling, domain metastability and hybrid domain-walls in two-dimensional CrI3 magnets
Dina Abdul-Wahab, Mathias Augustin, Samuel Manas Valero +9
Higher-order exchange interactions and quantum effects are widely known to play an important role in describing the properties of low-dimensional magnetic compounds. Here we identi…
Higher-order exchange interactions in two-dimensional magnets
Alexey Kartsev, Mathias Augustin, Richard F. L. Evans +2
Magnetism in recently discovered van der Waals materials has opened new avenues in the study of fundamental spin interactions in truly two-dimensions. A paramount question is what…
Ultrafast laser-driven topological spin textures on a 2D magnet
Mara Strungaru, Mathias Augustin, Elton J. G. Santos
Ultrafast laser excitations provide an efficient and low-power consumption alternative since different magnetic properties and topological spin states can be triggered and manipula…
Properties and dynamics of meron topological spin textures in the two-dimensional magnet CrCl3
Mathias Augustin, Sarah Jenkins, Richard F. L. Evans +2
Merons are nontrivial topological spin textures highly relevant for many phenomena in solid state physics. Despite their importance, direct observation of such vortex quasiparticle…
Thickness and twist angle dependent interlayer excitons in metal monochalcogenide heterostructures
Wenkai Zheng, Li Xiang, Felipe de Quesada +18
Interlayer excitons, or bound electron-hole pairs whose constituent quasiparticles are located in distinct stacked semiconducting layers, are being intensively studied in heterobil…
Magnetic field effect on topological spin excitations in CrI
Lebing Chen, Jae-Ho Chung, Matthew B. Stone +8
The search for topological spin excitations in recently discovered two-dimensional (2D) van der Waals (vdW) magnetic materials is important because of their potential applications…
Exfoliation of Two-Dimensional Nanosheets of Metal Diborides
Ahmed Yousaf, Matthew S. Gilliam, Shery L. Y. Chang +14
The metal diborides are a class of ceramic materials with crystal structures consisting of hexagonal sheets of boron atoms alternating with planes of metal atoms held together with…
Exciton-induced magnons carrying orbital angular momentum in CrI3
Martin Pavelka, Vishal Shokeen, Ruslan Chulkov +15
Magnons are collective spin excitations that contain and transport spin angular momentum in magnetic materials. It has been suggested that they can also carry orbital angular momen…
Room temperature ferromagnetism in intercalated Fe3-xGeTe2 van der Waals magnet
Hector Iturriaga, Luis M. Martinez, Thuc T. Mai +8
Among several well-known transition metal-based compounds, the van der Waals (vdW) Fe3-xGeTe2 (FGT) magnet is a strong candidate for use in two-dimensional (2D) magnetic devices du…
