Abstract

New transition metal polyborate, CoB₁₂O₁₄(OH) ₁₀ is synthesized by using boric acid as a flux. This material has isomorphic structure with MB₁₂O₁₄(OH)₁₀ (M Mg or Ni), consisting of two-dimensional borate layers and quasi-square lattice of Co²⁺. The Co²⁺ ions locate in the plane of the two-dimensional layer, bridged through B_nO_n+1 chains in the plane and connected with the three-membered ring borate groups out of the plane. The dc magnetic susceptibility and magnetization measurements show that the material undergo an antiferromagnetic phase transition at T_N 5 K. At T < T_N, a metamagnetic phase transition is observed at H _c 2 T, associated by a spin-flop. The structural and magnetic properties of the transition metal polyborate represent an example of interesting magnetic interaction in diluent magnetic systems.
