Overview
Deep microscopic understanding of electronic and magnetic properties by combining first-principles calculations with model theoretical analysis;
Microscopic mechanisms of coupling between electric polarization and magnetic structure in various multiferroic systems;
Unified microscopic theory of interatomic exchange interactions in complex magnetic materials
Novelty and originality
Systematic approach for the analysis and interpretation of the electronic structure calculations on the basis of microscopic models;
Theory of interatomic exchange interactions for the wide class of magnetic materials;
Superexchange theory for magnetically driven electric polarization in multiferroic systems
Details
Realistic model is derived from the first-principles calculations for the particular group of electronic states, which are primarily responsible for the considered phenomena and take into account all the advantage of these calculations by providing the material specific description, which is combined with the microscopic insight of the model analysis. The method was successfully applied for various types of materials and properties, including mutual control of the ferroelectricity and magnetism in multiferroic systems, the control of electric polarization and magnetism in compounds with complex skyrmionic structure, the design of magnetic systems without conventional 3d elements.
Summary
Besides deep fundamental understanding, the results can potentially used for developing novel electronic devices related to low-power nanoelectronics and data storage, as well as the synthesis of new type of magnetic materials without transition metal or rare earth elements. The developed computer packages can be applied for the wide class of magnetic materials.
