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.

La 1x Sr x MnO 3 nanoparticles were synthesized by precipitation from diethylene glycol solution. Features of synthesis were studied using 1 Н, 13 С, 139 La nuclear magnetic resonance (NMR) investigations. The obtained results showed that the complexation reaction between diethylene glycol and metal cations takes place during the synthesis. These complexes decomposed at 200 ℃ and an amorphous precursor (La,Sr)MnO 3 was formed. According to X-ray results, the crystallization of the perovskite structure began at 600 ℃ and finished at 800 ℃. Microstructural studies showed that obtained nanoparticles are weakly agglomerated and have small sizes. Based on these nanoparticles, magnetic fluid was prepared which was effectively heated under an alternating magnetic field.

Nickel cobalt ferrite, Ni 0.5 Co 0.5 Fe 2 O 4 , has been prepared by precursor combustion technique from hexahydrazine nickel cobalt ferrous succinate precursor. The precursor was characterized by chemical analysis, CHNS analysis, infrared spectroscopy, TG-DTA and mass loss studies. The thermal data show how the precursor decomposes in four steps to give stable ferrite phase. The precursor decomposes autocatalytically once initially ignited, to give the 'as-prepared' nano-spinel ferrite. The X-ray diffraction analysis reveals single cubic spinel phase structure. The infrared measurements between 4000 and 350 cm -1 confirmed the intrinsic cation vibrations of the spinel structure. The SEM image clearly shows the nanosized nature of the ferrite. The dielectric constant and loss tangent are found to decrease with increase in frequency which is due to Maxwell-Wagner interfacial polarization. The loss tangent shows a relaxation peak at *1 kHz. The variation of DC electrical resistivity with temperature indicates semiconductor behaviour. The temperature-and field-dependent magnetization data of 'as-prepared' ferrite reveal that the lattice has either a canted or partially misaligned spin structure due to the nanosized nature of the ferrite.
