Накратко на български
Спинтрониката изследва материали, при които се комбинират електроника и магнетизъм, като например полупроводниците с магнитни примеси. Те могат да станат основа за създаването на квантови компютри и по-ефективни информационни технологии.

Final Activity Report Summary - COMP. SPINTRONICS (Computational spintronics)
Spintronics combines the elements of electronics and magnetism into a new field that is expected to play an important role in applications in information technology. An example of such application is the spin field effect transistor (spin-FET) that could be the basic building block in quantum computers for the future. In order to facilitate a working device, suitable materials need to be found and in essence that was the main objective for the project. An important and promising class of materials that might be suitable are dilute magnetic semiconductors (DMS) like Ga1-xMnxAs and they are considered as ideal materials for spintronics. Only a few percent of Mn impurities are needed to achieve ferromagnetism. Thus the hope is that they can substitute the metallic ferromagnets to achieve all-semiconductor spintronics. In the project, a lot of attention has been put trying to understand this class of material starting from the fundamentals, the electronic structure, using state-of-the-art computational methods. In short, the most important results for the spintronics was a study of trends with respect to band filling of the exchange interactions responsible for magnetism in DMS and a proposed method to increase Curie temperature of DMS employing codoping of light interstitial atoms like Li. During the project, some new lines of research was also taken, namely studies of the well known Kondo effect of magnetic impurities in nonmagnetic metals and developing computational methods to calculate thermal properties like thermal conductivity and phonons for thermal barrier coating materials (TBC) and thermoelectric materials.

Цел на проекта
Spintronics, in which electronics and magnetism are combined, is attaining an increasing amount of interest due to its potential in applications. The proposed project focuses on searching for novel materials aimed for future applications in spintronics using state-of-the-art computational methods. The emphasis is put on finite temperature properties using Monte Carlo simulations and on electronic correlations using the dynamical mean field theory and density functional calculations, as implemented in the Korringa-Kohn-Rostoker (KKR) method.These methods will further be developed on the IBM Blue Gene supercomputer at the Research Centre Julich. During the previous work the researcher has established his expertise in many areas of magnetism, including diluted magnetic semiconductors, magnetic multi-layers, non-collinear magnetism and in statistical methods. With the proposed project the researcher shall complete his knowledge about magnetism and will learn more about electronic structure theory. He will learn a completely new field of strongly correlated systems.The interest in strong correlations in magnetic systems is increasing rapidly so that the researcher shall benefit a lot from the methods and problems that he will learn. The stay in Germany should create many new contracts for the researcher that will help him in his future work. The complementary skills like increased responsibility and independence of the research are very important in promoting further the scientific career of the candidate. The aspects of transnational mobility will result in the information exchange between Sweden and Germany and help in developing the European research area.
