    Mössbauer study of thermal magnetic transitions in Cu0.5Zn0.5Fe2O4

    The dependence of the Mössbauer spectra of the ferrite Cu0.5Zn0.5Fe2O4 on the temperature is investigated. The profiles of the hyperfine magnetic fields distributionP(H) are obtained from the spectra by a decompo...

    On the advantages and validity of the method of decomposition of Mössbauer spectra from amorphous and disordered magnetic materials

    A method for decomposition of Mössbauer spectra of amorphous and disordered magnetic materials is tested. Its algorithm is discussed as well as the adaptation of the method for processing of more complex spect...

    On the hyperfine magnetic field distribution at118Sn in spinel ferrites

    The distributionP(H) of the hyperfine magnetic fieldsH at the119Sn nucleus in spinel ferrites can be reliably obtained by means of the decomposition method [10] adapted for this case. To interpretP(H), a polynomi...

    Detailed Mössbauer study of the cation distribution in CoFe2O4 ferrites

    Partially inverted (Co0.185Fe0.815)[Co0.815Fe1.185]O4 spinel submicron particles with spherical shape are studied at low temperature by Mössbauer spectroscopy. Canted magnetic structures are evidenced. The hyperf...
