Abstract
Field-induced commensurate transverse magnetic ordering is observed in the Haldane-gap compound Ni(C5D14N2)(2)N-3(PF6) by means of neutron diffraction . Depending on the direction of applied field, the high-field phase is show n to be either a three-dimensional ordered Neel state or a short-range orde red state with dominant two-dimensional spin correlations. The structure of the high-field phase is determined, and properties of the observed quantum phase transition are discussed.
