We have recently completed 4 days on EMU investigating the evolution of local magnetic states in the expanded metal, lithium amine systems. Our results are promising. However, the study of these mixed amine systems was hindered by the necessity for in situ preparation. The difficulties encountered can be avoided by the use of high momentum muons on ARGUS allowing for off-site preparation of samples in bespoke quartz containers. We aim to probe the evolution of local magnetic states in Li(MeNH2)4 and consolidate indications that Li(NH3)2(MeNH2)2 has distinctly different magnetic character to the parent amines.
