Abstract

Inelastic neutron scattering measurements have been performed on single crystal samples of Co3V2O8 and Ni3V2O8. The magnetic system in these compounds is believed to be frustrated, as the magnetic ions (Co2+ with S = 3/2 and Ni2+ with S = 1) adopt a buckled version of the Kagome lattice. Magnetic excitations have been observed in both samples using a time-of-flight neutron spectrometer. The excitation spectrum is dispersive for both samples and has a considerable gap in the low-temperature phases, while the intermediate temperature phases are marked by a significant softening of the excitations energy.
