З’ясування природи фізичних процесів, які відбуваються під час переходу до нано до макро розмірів при синтезі феритових матеріалів та встановлення закономірностей зміни властивостей наночастинок і полікристалічних матеріалів залежно від рівня легування.

VI Vernadsky National Academy of Sciences of Ukraine popup.description1 The aim of thos project is synthesis of nanoscale particles and polycrystalline samples based on the ferrites with the garnet structure, which can be used for the development of the devices for communication systems, and study of the structural and physichochemical parameters of the synthesized materials. popup.description2 The synthesis and investigation of Al- and Gd-substituted yttrium iron garnets have been carried out. The principal correlations between the synthesis conditions of nanoparticles, phase formation processes in the system, and the structural and magnetic properties of the resulting powders and polycrystalline materials based on the developed ferrites have been established. It has been demonstrated that the combination of sequential precipitation with targeted substitution by gadolinium cations opens new opportunities for the development of garnet ferrites with enhanced microwave characteristics and improved technological processability. The obtained results not only deepen the fundamental understanding of garnet phase formation as a function of gadolinium concentration, but also propose a scalable route for producing high-performance polycrystalline ferrites with low porosity, suitable for application in modern microwave and millimeter-wave devices.
