We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field measured at 40K and that some form of magnetoelectric coupling exists at 300 K. A draft of a paper was circulated 2 weeks after we finished the experiment and we wish to submit asap. However, there are still questions that require answering. Why is there little change in the relaxation rate during the hysteresis loop? Why is there a departure from the normal temperature dependence to the internal field of the AFM? What is the origin of the 300 K magnetoelectric coupling? Is there any intrinsic 300 K magnetoelectric coupling, or is it only present when the electric field is applied at low temperatures and the sample is heated? These are questions we will begin to address in this proposal.
