    • Spin Excitations in Co3V2O8. Raw data files from neutron spectroscopy experiments using the DCS spectrometer at the NCNR to probe the spin fluctuation spectrum of Co3V2O8.

    Metadata Updated: July 29, 2022

    A series of neutron spectroscopy measurements were performed on two single crystal samples of Co3V2O8 using the Disk Chopper Spectrometer (DCS) time-of-flight neutron spectrometer at the NIST Center for Neutron Research. In the low-temperature ferromagnetic phase spin waves are observed throughout the Brillouin zone. Modelling the spin wave dispersion reveals significant magnetic interaction between buckled kagome planes, contrary to prior work which treated the compound as quasi-two-dimensional. Further, the spin wave branches show evidence of a surprisingly large Dzyaloshinskii-Moriya interaction. At T=9.2 K the sample is antiferromagnetically aligned and well-defined spin waves are not observed. Rather, most of the spectral weight is observed in broad diffuse scattering centered at the (0 0.5 0) antiferromagnetic Bragg peak.

    The raw data files and parameter files from these experiments are provided here. The data can be analyzed using the DCS Reduction (Mslice) capabilities of the DAVE software package available at https://www.ncnr.nist.gov/dave/.
