Bentonite/Iron Oxide Composites: Preparation and Characterization by Hyperfine Methods
Figure 1
Left: the room temperature 57Fe Mössbauer spectra measured in zero external magnetic field, experiment (symbols), and fit (lines). Right: differences between the successive spectra. In both parts of the figure, positions of spectral lines in sextets of well-crystallized hematite and maghemite calculated from hyperfine parameters in [7] are marked by short vertical lines (red lines, hematite; green lines, maghemite).
