dc.description.abstract | De-magnetization and heat capacity measurements on polycrystalline samples of SrNi2-xMgxV2O8 (x = 0 and 0.05) are reported. The magnetization data suggest that both compounds are S= 1 quasi one-dimensional Heisenberg antiferromagnets. The substitution of non-magnetic impurity Mg2+ ions for Ni2+ induces a magnetic phase transition at ∼3.7 K. A simple Hamiltonian model is proposed for these systems giving good quantitative agreement with the experimental magnetization data. The intrachain magnetic exchange constant (J1/kB) and the Haldane gap (Δ) for both compounds are estimated to be ∼ 105 K and ∼ 58.3 K (5.02 meV), respectively. © 2006 WILEY-VCH Verlag GmbH & Co.
