“…Metal borates are expected to be good candidates to serve as links for transition metal polyhedra giving rise to different low-dimensional structures 7 . Another important role of the borate anions, being non-magnetic, is to allow transmission of magnetic interactions via a super-superexchange route [8][9][10][11] .…”

Long range antiferromagnetic (AFM) ordering of Ni spins in Ni2NbBO6 has been studied with single crystal from spin susceptibility measurement and compared with the ab initio calculation results consistently. Below T N∼23.5 K, the S = 1 spins align along the a-direction for edge-shared NiO6 octahedra which form crystallographic armchair chains along the b-direction. The isothermal magnetization M (H) below TN shows spin-flop transition for magnetic field above ∼ 36 kOe along the a-axis, which indicates the spin anisotropy is along the a-direction. The electronic and magnetic structures of Ni2NbBO6 have also been explored theoretically using density functional theory with generalized gradient approximation plus on-site Coulomb interaction (U). These calculations support the experimentally observed antiferromagnetism of Ni2NbBO6. In particular, the long range AFM ordering below TN can be dissected into armchair chains which consists of S = 1 dimers of J2∼2.43 meV with ferromagnetic (FM) intra-chain and inter-chain couplings of size 1 2 |J2|.

“…4-7 A second point of interest derives from the fact that borate anions have been well known to mediate magnetic exchange interactions between bridged magnetic ions. [8][9][10][11] The important roles of the borate groups, though being nonmagnetic, are not only to fix the metal ions into the desired structure, but also to transmit magnetic interactions between the individual metal ions via a superexchange mechanism. A pioneering work by Kageyama et al, reveals singular quantized magnetization plateaus in SrCu 2 (BO 3 ) 2 with a ground state of the Cu dimer mediated by planar BO 3 .…”

A new nickel polyborate, NiB12O14(OH)10 was synthesized using boric acid as a flux. This material has two-dimensional borate layers with a quasi-square lattice of Ni2+. The Ni2+ ions locate in the plane of the two-dimensional layer, bridged through BnO(n+1) chains in the plane and connected with the three-membered ring borate groups out of the plane. The dc and ac magnetic susceptibility, magnetization and specific heat measurements show that this material undergoes a weak ferromagnetic phase transition at Tc = 5.8 K. At T < Tc, a metamagnetic phase transition is observed at about 5 T, associated by a spin-flop, suggesting the ferromagnetic ordering is induced by an antiferromagnetic interaction. A broad maximum in the ac susceptibility at TM = 23-24 K indicates an intermediate short-range ordering.
