Project Goal
The goal of the project is to further develop the theory and practice of synthesizing new nanosized magnetic multicomponent oxide multiferroics based on perovskites, as well as to investigate their structure and physicochemical characteristics. The project is aimed at understanding their potential for applications in various technological fields, including electronics, spintronics, information storage, and sensing.
Project Tasks
To achieve the project goal, the following tasks will be addressed:
Task 1: Synthesis of Multicomponent Manganites in Polycrystalline and Nanograined States
1.1. Study of Optimal Synthesis Conditions for New Multicomponent Magnetic Materials Based on Mixed Manganites:
- Conduct a literature review of existing synthesis methods for mixed manganites with perovskite-like structures.

- Determine the optimal synthesis conditions for producing target multicomponent manganites with specified characteristics.
1.2. Synthesis and Study of Physicochemical Properties of Nanosized Multiferroics Based on Perovskite-like Structures:
- Develop synthesis methodologies for nanomaterials with controlled sizes and shapes (e.g., sol-gel, hydrothermal, co-precipitation, etc.).
- Study the impact of size effects on the structure, magnetic, electrical, and other properties of the synthesized nanomaterials.
- Investigate the relationship between composition, structure, and physicochemical characteristics of new nanocomposite multiferroics.
1.3. Optimization of Obtained Results:
- Analyze and summarize the data collected.
- Identify patterns between synthesis conditions, composition, structure, and functional properties of the new perovskites.
