PROIECTULUI: 2005 - 2008
2. Studies of nanodimensional magnetic particles by ferromagnetic resonance and Mossbauer spectroscopies. Size effects will be investigated on samples with narrow size distributions. Dynamic effects will be deduced from temperature dependences, and surface effects will be determined from these data.
3. Studies of magnetic and structural properties of metalic nanowires. Growing methods will be improved, and careful characterization of obtained samples will be made. The spin dynamics will be deduced from EPR data, and dipolar interaction will be investigated experimentally and a theoretical model will be proposed.
4. Volume and surface defects at the interface of thin films of organic semiconductor Alq3 and other compounds Meq3 will be studied by magnetic resonance and structural methods. The nature of paramagnetic defects produced by various ways, and electrochemically induced in structured Alq3-substrate will be determined. Relevant data for its use in OLED devices are in view.5. Defects at semiconductor-isolator interface will be studied by magnetic resonance and FT-IR. Mettalic clusters embedded in inert matrices will be investigated, and size and dimensionality effects will be evidenced.
• By these researches, fundamental understanding of a few classes of disordered solids is developed and new knowledge on advanced materials are obtained. A new methodology of spectroscopic data interpretation based on local disorder simulation will be developed. This experience will be diseminated to other reserch groups not involved in this project. A basis for promoting our research groups participation in European Programs will be also achieved. The contribution of young researchers is essential and the project will contribute to their scientific education and development.
