Modified anisotropy and distinct phase diagrams in the nearly isotropic triangular-lattice antiferromagnet
Xuejuan Gui, Xu-Guang Zhou, Chen Zhang +13
The triangular-lattice antiferromagnet serves as a benchmark platform for realizing exotic quantum phases, in which magnetic anisotropy plays an essential role. In this work, we re…
Universality of the Magnetization Plateau and Quantum-Disordered States in the Kagome Family (; )
