Influence of Barium Intercalated Ions on Magnetic Interaction in the Tellurate Compound BaNi2TeO6

A novel transition metal tellurate single-crystalBaNi2TeO6with layered honeycomb lattices has been successfullysynthesized. The crystal structure of BaNi2TeO6reveals that thereare the Ni2+honeycomb lattice layers and Te6+triangle latticelayers in theabplane. BaNi2TeO6shows an antiferromagnetic(AFM) transition at similar to 25 K, which is almost the same temperatureas the Curie-Weiss temperature theta similar to-27 K, indicating thepresence of the AFM interactions without obvious magneticfrustration in the system. However, thefield-induced successivemagnetic transitions observed atHc1 similar to 16.2 T andHc2 similar to 42.2 Tshow the complicated spin structure in BaNi2TeO6. Compared with the isostructural Na2Ni2TeO6, the various magnetic propertiesindicate that the intercalated ions (Ba2+) can significantly affect the magnetic properties of the layered honeycomb lattices, whichmay be useful for exploring the spin-liquid state and valence bond liquid state in the layered honeycomb lattice compounds.

Automated summary

A novel transition metal tellurate single-crystal BaNi2TeO6 with layered honeycomb lattices has been successfully synthesized. The crystal structure reveals the presence of Ni2+ honeycomb lattice layers and Te6+ triangle lattice layers. BaNi2TeO6 exhibits an antiferromagnetic transition at around 25K and field-induced magnetic transitions at 16.2T and 42.2T, indicating a complex spin structure. The magnetic properties of BaNi2TeO6 are significantly influenced by intercalated ions, Ba2+, compared to the isostructural Na2Ni2TeO6.
