“…The structure of the Al 2 O 3 substrate material as the investigating methods of magnetic properties of the thin film structures were reported in our previous studies [ 22 , 30 , 31 ]. It should be noted that when scanning the maximum possible area of 100 × 100 μm 2 , the surface consists of particles with sizes of 50–600 nm and height differences of 800 nm ( Figure 5 ).…”

In this study, the synthesis and magnetic properties of the rare-earth iron garnets Sm3Fe5O12, Pr3Fe5O12, and Er3Fe5O12 (in the form of powders and thin films) are reported. According to the composition, shape, and size of particles, the optimal precipitant for the synthesis of Sm3Fe5O12, Pr3Fe5O12, and Er3Fe5O12 films is an aqueous solution. The parameters for the synthesis of powders and films of the rare-earth iron garnets with micro- and nano-particles have been investigated and selected. The magnetic properties of these materials were studied; field dependencies of the magnetic moment (hysteresis loops) of nanostructured powders of iron garnets of samarium, praseodymium, and erbium in the range of +20 kOe to −20 kOe were obtained. The structural features of the Al2O3 substrate on which the films were formed are also shown.

The synthesis of nanostructured powders and films based on rare-earth ferrite garnet Sm3Fe5O12 was carried out with hydrothermal as well as with the method of precipitation of aqueous solutions of nitrates on the substrate surface. Using atomic force microscopy (AFM), scanning electron microscopy (SEM), Raman spectroscopy (Raman), and X-ray phase analysis (XRD), the topology of the surface and the phase composition of the samples were studied. According to AFM and SEM, particle sizes were evaluated and the structural features of powders and films were analyzed. Raman spectroscopy (RS) and X-ray phase analysis were used to examine the chemical composition and crystal structures of synthesized samples. The possibility of simultaneous investigation of the same sample area with AFM methods and Raman spectroscopy made it possible to obtain data of the chemical composition, the presence of impurities and defects, and the shape of macromolecules. Taking into account the set of obtained results, it is shown that materials based on Sm3Fe5O12, due to their structural features and physics-chemical parameters, can be used as filters for industrial sewage treatment.
