Berezinskii-Kosterlitz-Thouless Phase in Two-dimensional Ferroelectrics
Changsong Xu, Yousra Nahas, Sergei Prokhorenko +2
The celebrated Berezinskii-Kosterlitz-Thouless (BKT) phase transition refers to a topological transition characterized, e.g., by the dissociation of vortex-antivortex pairs in two-…
Possible Kitaev Quantum Spin Liquid State in 2D Materials with S=3/2
Changsong Xu, Junsheng Feng, Mitsuaki Kawamura +6
Quantum spin liquids (QSLs) form an extremely unusual magnetic state in which the spins are highly correlated and fluctuate coherently down to the lowest temperatures, but without…
Magnetic Skyrmion State in Janus Monolayers of Chromium Trihalides Cr(I,X)3
Changsong Xu, Junsheng Feng, Hongjun Xiang +1
Magnetic skyrmions are nano-scale spin structures that are promising for ultra-dense memory and logic devices. Recent progresses in two-dimensional magnets encourage the idea to re…
Magnetic Interactions in BiFeO: a First-Principles Study
Changsong Xu, Bin Xu, Bertrand Dupé +1
First-principles calculations, in combination with the four-state energy mapping method, are performed to extract the magnetic interaction parameters of multiferroic BiFeO. Suc…
Interplay between Kitaev interaction and single ion anisotropy in ferromagnetic CrI and CrGeTe monolayers
Changsong Xu, Junsheng Feng, Hongjun Xiang +1
Magnetic anisotropy is crucially important for the stabilization of two-dimensional (2D) magnetism, which is rare in nature but highly desirable in spintronics and for advancing fu…
