Abstract

Two quasi-one-dimensional S=1 quantum antiferromagnetic materials, PbNi₂V₂O₈ and SrNi₂V₂O₈, are studied by inelastic neutron scattering on powder samples. A simple model Hamiltonian is proposed for the two systems and used to analyze the data. Quantitative information on in-chain and interchain interactions obtained from this analysis is discussed in the context of qualitatively different ground-state properties: magnetic long-range order in SrNi₂V₂O₈ and disordered "spin liquid" Haldane-gap state in PbNi₂V₂O₈.
