Description

We report results of a single-crystal Raman scattering study of the coupled spin-1 Haldane chain compound SrNi2V2O8. In addition to the one-and two-magnon excitations, broad gapless and temperature dependent continua are detected with light polarization parallel to the basal plane. This feature is discussed in terms of spinon-like excitations related to a symmetry protected topological state, of which the Haldane phase in 1D is a preeminent example.
