Abstract

A novel transition metal tellurate single-crystal BaNiTeO with layered honeycomb lattices has been successfully synthesized. The crystal structure of BaNiTeO reveals that there are the Ni honeycomb lattice layers and Te triangle lattice layers in the plane. BaNiTeO shows an antiferromagnetic (AFM) transition at ∼25 K, which is almost the same temperature as the Curie-Weiss temperature θ ∼ -27 K, indicating the presence of the AFM interactions without obvious magnetic frustration in the system. However, the field-induced successive magnetic transitions observed at ∼ 16.2 T and ∼ 42.2 T show the complicated spin structure in BaNiTeO. Compared with the isostructural NaNiTeO, the various magnetic properties indicate that the intercalated ions (Ba) can significantly affect the magnetic properties of the layered honeycomb lattices, which may be useful for exploring the spin-liquid state and valence bond liquid state in the layered honeycomb lattice compounds.

摘要

一种具有层状蜂窝晶格的新型过渡金属碲酸盐单晶BaNiTeO已成功合成。BaNiTeO的晶体结构表明，在平面内存在Ni蜂窝晶格层和Te三角形晶格层。BaNiTeO在约25 K时显示出反铁磁（AFM）转变，这几乎与居里-外斯温度θ ∼ -27 K相同，表明系统中存在AFM相互作用且没有明显的磁阻挫。然而，在约16.2 T和约42.2 T时观察到的场致连续磁转变表明BaNiTeO中存在复杂的自旋结构。与同结构的NaNiTeO相比，各种磁性表明插入离子（Ba）可显著影响层状蜂窝晶格的磁性，这可能有助于探索层状蜂窝晶格化合物中的自旋液体态和价键液体态。
