Modeling Bond-Dependent Kitaev-like interaction in 2D Edge-Sharing Tetrahedral Magnets: FeX (X=Te, Se)
Mengdong Li, Can Huangb, Bingjie Liu +6
Bond-dependent magnetic interactions, exemplified by the Kitaev model, are known to arise from the interplay between spin-orbit coupling (SOC) and specific coordination geometries,…

Stabilization of zigzag order in NiPS via positive biquadratic interaction
Qiang Luo, Shuhang Yang, Xiaoying Wang +4
Despite extensive research, the precise spin Hamiltonian of the van der Waals antiferromagnet NiPS -- which hosts a zigzag-ordered ground state -- remains debated. While consen…
