A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic" ferroelectric and multiferroic. We have previously performed triple axis spectrometer experiments on a small single crystal finding 3 or 4 magnetic modes dispersing up to energies of 60meV. Now we have grown a larger (> 10 times) single crystal and - using neutron Time-of-Flight spectrometry - aim to map the excitation spectrum throughout the entire Brillouin zone of LuFe2O4. This will expand upon and clarify the inconclusive triple-axis results with the lower energy modes proving very difficult to accurately resolve. Current spinwave theory predicts 2 or 3 further modes at higher energies which are yet to be found.
