beta-Mn metal is a good example of metal close to a magnetic/non-magnetic instability. It doesn't order magnetically at any temperature, and yet has a large Somerfeld constant, and NMR relaxation properties consistent with large amplitude magnetic fluctuations. Our previous neutron scattering investigations of powder samples revealed that the spin-fluctuations in pure beta-Mn exhibit strong non-lorenztian relaxation properties and non-Fermi-liquid scaling with temperature. However, it is possible that in a powder, this apparent behaviour is an artefact caused by a powder average over a range of linewidths. We now have a large (2 cm^3) single crystal of Mn, stabilised in the beta-phase with 25at% Co, which we wish to use the MERLIN spectrometer in order to characterise both the shape and the Q-dependence of the high-frequency spin-dynamics of this fascinating element.
