Goal and objectives of the project

- Using neutron diffraction method on nuclear reactor IBR-2 to study crystal structure and magnetic structures of some materials.
- Enhance the knowledge of Vietnamese researchers about neutron diffraction method for application in materials research.
-Strengthening the exploitation of the large research facilities at the Institute for Nuclear Research.

Main results

- Obtaining several new results on the structural state and magnetic order state of BaYFeO4 and Mn3O4 oxide complex electromagnetic materials according to the change of temperature parameters and chemical composition using neutron diffraction method. The scientific content of these results has been published in 05 scientific articles published in ISI journals with high impact factor.
- Enhance the knowledge of Vietnamese researchers about neutron diffraction method for application in materials research.
-Strengthening the exploitation of the large research facilities at the Institute for Nuclear Research.
- Enhance the international cooperation between Vietnam and Russian Federation.

Novelty and actuality and scientific meaningfulness of the results

The new obtained experimental results have important implications for development of simulation models of the properties of ferroelectric materials and can be used for ab-initio calculations. The obtained results contribute to the elucidation of the physical nature of the magnetic-electrical effects and contribute to the future application of multiferroics materials.
