Applications of Mössbauer Spectroscopy to Studies of Quasicrystals [PDF]
, 2008 A review is presented of the application of the Mössbauer spectroscopy to the study of quasicrystals. The usefulness of the Mössbauer spectroscopy to solving the atomic structure of a complex icosahedral system is illustrated.

Mössbauer Study of Weathered H-meteorite from the Desert of Oman
Sultan Qaboos University Journal for ScienceA number of meteorites from the desert of Oman, classified as H-chondrites, with known and unknown ages, were studied by using 57Fe Mössbauer spectroscopy to determine their Fe3+-bearing compositions.

Small Methods, EarlyView.In situ and operando XAS is used to probe nanoparticle formation during chemical vapor synthesis, where particles form in the gas phase under high‐temperature conditions. XANES reveals dynamic changes to the oxidation states while EXAFS indicates local structural variations under in situ probing conditions.

Estudio Minerológico de Suelos Agrícolas por Espectroscopia Mössbauer
Revista de Investigación de Física, 1999 Los compuestos de hierro (Fe) son muy comunes en la naturaleza. En el caso de suelos, se presenta en forma de sesquióxidos de hierro, tales como óxidos, hidróxidos y oxihidróxidos, así como cationes de sustitución en arcillas.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.
