Notes:
The factors influencing the chemical isomer shift, quadrupole splitting and hyperfine magnetic interactions, are briefly summarized and applications to solid state systems reviewed. New results on the disordered rutile phases Fe2MgF6, FeMg2F6, and FeCoNiF2, and on the trirutile phase Li+ Fe2+ Fe3+ F6 are presented to illustrate the power of the Mössbauer technique in probing details of oxidation states, site symmetries and magnetic ordering. An extensive study on the nonstoichiometric wüstite phase Fe1-xO is also reported and analyzed in terms of diffusion broadening at high temperatures and defect clustering in quenched samples; the production of essentially stoichiometric FeO by annealing is also discussed. Recent results on the application of large external magnetic fields to diamagnetic compounds of tin are reviewed and results of a Mössbauer investigation of lunar samples returned by the Apollo 11 and 12 missions are discussed.
