Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the discovery of themagnon Hall effect in the ordered phase, and a large magneto-resistance above Tc. Here we areproposing to continue our study of the magnetic excitations in Lu2V2O7 on MERLIN. Our first experiment was very successful and has allowed us to fix the basic parameters of the Hamiltonian. This experiment will be focussed on providing a definitive understanding of the role of the Dzyaloshinskii-­Moriya interaction, which is key to understanding the properties of Lu2V2O7.
