The effects of magnetic dilution on the magnetism in the two-dimensional (2D) oxide systems Sr1 +xLa1 –x Fe1 –xSnxO4 and SrLaFe1 –xGaxO4 have been studied by Mossbauer spectroscopy and magnetometry. The end-member, SrLaFeO4, has a Neel temperat

Extracts from Point of Ayr coal prepared in two ways [in a flowing solvent (tetralin) liquefaction experiment and the coal digest from the British Coal pilot plant at Point of Ayr] have been examined by Mossbauer spectroscopy to investigate the chemi

The perovskite-related oxide Ca2Fe2O5 takes up additional oxygen under high pressure and elevated temperature. The Mossbauer spectra from a number of preparations establish the existence of new phases which are structurally related to the original la

The cubic perovskite solid solution Sr2FeSnO5.71, which contains both Fe3+ and Fe4+ cations, has been shown to be a spin-glass by a combination of magnetic susceptibility with 57Fe and 119Sn Mossbauer spectroscopic measurements. The zero-field-cooled
