Modified anisotropy and distinct phase diagrams in the nearly isotropic $S = 1$ triangular-lattice antiferromagnet $R b_{2} Ni (Se O_{3})_{2}$

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…

Low-energy spin dynamics in a Kitaev material Na3Ni2BiO6 investigated by NMR

Xinyu Shi, Yi Cui, Yanyan Shangguan +11

We performed 23Na NMR and magnetization measurements on an S = 1, quasi-2D honeycomb lattice antiferromagnet Na3Ni2BiO6. A large positive Curie-Weiss constant of 22.9 K is observed…

Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice

Jieming Sheng, Jia-Wei Mei, Le Wang +31

In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…

Spin frustration and magnetic ordering in triangular lattice antiferromagnet Ca $_{3}$ CoNb $_{2}$ O $_{9}$

J. Dai, P. Zhou, P. S. Wang +5

We synthesized a quasi-two-dimensional distorted triangular lattice antiferromagnet Ca $_{3}$ CoNb $_{2}$ O $_{9}$ , in which the effective spin of Co $^{2 +}$ is 1/2 at low temperatures, whose…
