The room temperature Mössbauer spectrum () of Sono-STFO40 consists in the superposition of two components: a prevailing central quadrupole doublet (continuous line in blue) assigned  to Sr(Ti0.6Fe0.4)O2.845 and a complex magnetic hyperfine component associated with five iron sites (12k, 4f1, 4f2, 2a and 2b) in the SrFe12O19 structure  (continuous color sextet lines). The continuous lines in represent the computer fit of the experimental points in the hypothesis of Lorentzian line shape. This result is in good agreement with the XRD data.

Iron oxide NPs with controlled size and shape are technologically important due to strong correlation between these parameters and magnetic properties. The microemulsion and thermal decomposition methods usually lead to complicated process or require relatively high temperatures. As an alternative, hydrothermal synthesis includes various wet-chemical technologies of crystallizing substance in a sealed container from the high temperature aqueous solution (generally in the range from 130 to 250 °C) at high vapor pressure (generally in the range from 0.3 to 4 MPa). This technique has also been used to grow dislocation-free single crystal particles, and grains formed in this process could have a better crystallinity than those from other processes, so hydrothermal synthesis is prone to obtain the highly crystalline iron oxide NPs.
