In order to find a relationship between electrical and microstructural properties, yttrium-doped strontium titanate (7 mol%) with various values of strontium nonstoichiometry was investigated and shown in this work. It has been observed that yttrium doping can affect the electrical properties of SrTiO3 to a great extent. Moreover, the microstructural and electrical properties can be influenced by strontium nonstoichiometry. The defect chemistry explaining obtained results was also suggested and discussed.

The aim of the study was to characterize the 0.8CaZrO3-0.2CaFe2O4 composite structure with particular emphasis on the role and position of iron in the function of sintering temperature. The paper presents the results of 57Fe Mössbauer effect at room temperature. It was found that the increase of sintering temperature causes an increase in the amount of incorporated iron ions in the CaZrO3-crystal structure. Based on Mössbauer spectroscopy analysis, it was found that three different environments of Fe3+ ions were observed in the obtained materials. Two of them corresponded to CaFe2O4 phase and one was associated with the substitution of Zr4+ by Fe3+ in the CaZrO3 structure.

The work highlights peculiar features of synthesis and summarizes important properties of nanoparticles and films based on two types of oxide magnets: with spinel and perovskite-type structures. The attention is drawn to the differences in the processes underlying the formation of crystalline phase in the materials of each group. It is shown that for the spinels, the formation of weakly agglomerated crystalline nanoparticles can occur in the process of synthesis, but for the perovskite-like magnets, the formation of crystalline nanoparticles requires additional high-temperature treatment. It is demonstrated that synthesized nanoparticles and films may find wide practical applications, particularly as the heat mediators in hyperthermia treatment therapy, as components of left-handed media, ferroelectric-ferromagnetic layered structures and composite microwave resonators. They also may be used as integral parts of composite structures, which possess magnetic-field-controlled properties and display giant magnetocaloric effect.
