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.
