Abstract
We report a quasi-one-dimensional S=1 spin chain compound BaNiTe2O7. This magnetic system has been investigated by magnetic susceptibility, specific heat, and neutron powder diffraction. These results indicate that BaNiTe2O7 develops a short-range magnetic correlation around T∼22K. With further cooling, an antiferromagnetic phase transition is observed at TN∼5.4K. Neutron powder diffraction revealed antiferromagnetic noncollinear order with a commensurate propagation vector k=(1/2,1,0). The refined magnetic moment size of Ni2+ at 1.5 K is 1.84μB, and its noncollinear spin texture is confirmed by first-principles calculations. Inelastic neutron-scattering results and density functional theory calculations confirmed the quasi-one-dimensional nature of the spin systems.
