Figure 2. (a) shows the relative area of magnetically split
Smagn components (%) in the
Mössbauer spectra of the films with different iron oxide concentrations (Cv).
The shaded rectangles denote the rock compositions whose spectra are represented by
a superparamagnetic (SP) doublet; (b) the saturation magnetization values (Js) for
the films with different volumetric
Cv concentrations: the black circles
denote the values of specific saturation magnetization of the films (Jsf);
the blue squares, the specific saturation magnetization of nanoparticles calculated using
the weight content of magnetite
Cp , the latter was estimated proceeding from the contents
of the components developed in the course of the film synthesis; the red solid
circles denote the specific saturation magnetization of real maghemite particles (for
Cv values lower than or
equal to 11%) and those of magnetite (for
Cv values lower than or equal to 20%). These calculations were
made only using corrections for the magnetically ordered particles in the samples (Figure 2a). The broken
lines are drawn to mark the values characteristic of maghemite and magnetite bulk compositions. The
shaded rectangle is shown for the values, most of the spectra of which were represented by SP doublets.
Therefore, the correction procedure involving
Smagn could not be performed or was associated with
significant errors.
