Title:
Spin-{{Vacancy}}-{{Induced Long}}-{{Range Order}} in a {{New Haldane}}-{{Gap Antiferromagnet}} 
Abstract:
Magnetic susceptibility, high-field magnetization, and inelastic neutron scattering experiments are used to study the magnetic properties of a new S=1 quasi-one-dimensional antiferromagnet PbNi2V2O8. Interchain interactions are shown to be almost, but not quite, strong enough to destroy the nonmagnetic singlet ground state and the energy gap in the magnetic excitation spectrum. Substituting nonmagnetic Mg2+ ( S=0) ions for Ni2+ ( S=1) induces a magnetically ordered state at low temperatures. To...    »
