摘要：

The effect of the impurity doping in the quantum-spin chains of the PbNi2V2O8 Haldane-gap compound is studied. We report elastic neutron scattering and bulk magnetic susceptibility measurements on the quasi-one-dimensional system PbNi(2-x)A(x)V(2)O(8) doped at the Ni2+ (S = 1) sites by either non-magnetic A = Mg2+ (S = 0) or magnetic A = Co2+ (S = 3/2) ions, with x = 0.12 and 0.08, respectively. The results reveal that the magnitude of the Neel temperature depends strongly on the spin value of the A cation.
