    Magnetic properties of ferrihydrite (1986)
    Springer
    Hyperfine interactions 27 (1986), S. 329-332

    Topics: Physics
    Notes: Abstract The magnetic properties of a sample of synthetic ferrihydrite have been investigated by use of Mössbauer spectroscopy. The area ratios of the Mössbauer lines are not significantly changed by application of magnetic fields at 5 K, indicating an amorphous magnetic structure. An average magnetic moment per particle of 3.1×10−21 JT−1 was estimated from the dependence of the hyperfine splitting of the Mössbauer spectra on external magnetic fields at 80 K.

    Decoupling of magnetically interacting crystallites of goethite (1986)
    Springer
    Hyperfine interactions 28 (1986), S. 549-552 
    Details
    ISSN: 1572-9540
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The magnetic properties of synthetic goethite, precipitated from a SiO2-containing Fe(III) solution, have been studied. The Mössbauer spectra show the coexistence of a quadrupole doublet and a magnetically split component in a large temperature range. The area ratio of these two components depends strongly on temperature, indicating a normal superparamagnetic behaviour of isolated crystallites. This is in contrast to the behaviour normally exhibited by pure samples of microcrystalline goethite, in which strong magnetic interactions among the crystallites lead to a superferromagnetic behaviour. The results show that the magnetic interactions among the crystallites are drastically diminished when amorphous SiO2 separates the goethite crystallites.

    A study of the sump beaver's dental enamel (1986)
    Springer
    Hyperfine interactions 29 (1986), S. 1431-1434

    Topics: Physics
    Notes: Abstract The nature of the iron-containing phase in the dental enamel of sump beaver incisors has been studied by use of Mössbauer spectroscopy. All iron atoms are found to be trivalent and to be present in particles exhibiting superparamagnetic relaxation. The iron-containing phase has Mössbauer parameters similar to those of ferritin.
