Magnetic behaviors of Cu3TeO6 with multiple spin lattices

• Large-sized single crystals of Cu3TeO6 are grown by flux method.
• No magnetic anisotropy and spin frustration are confirmed in the system.
• Possible spin arrangements are suggested for spin–lattices in the system.

Spin-web compound Cu3TeO6 exhibits many remarkable geometrical-frustration lattices including spin equilateral-triangle, spin isosceles-triangle, and spin planar-hexagon. Large single crystals of Cu3TeO6 are successfully grown at slow cooling rate using flux method in an alumina crucible. The grown crystals show unique growth behaviors and morphology. The quality of the crystals is confirmed using X-ray powder diffraction technique. Magnetic behaviors of the grown crystals are investigated by means of magnetic and heat capacity measurements, showing a long-range antiferromagnetic ordering at ~60 K. Base on experimental results, the spin arrangements for each spin–lattice in Cu3TeO6 are also suggested.
