Postgraduate researcher, winner of the Tatarstan Academy of Sciences scholarship Anna Ivanova speaks about her participation in the project.
«I study ferriferous complexes, - says Anna. – Some transition metal complexes show the spin effect – the phenomenon of spin state changing from external factors, such as temperature, pressure, radiation, and magnetism».
These complexes can be used to produce detectors, converters, switching units – all based on as little as a single molecule. Ms. Ivanova's research has to do with such miniaturization.
«There are now many ideas on modifying such complexes in order to make them suitable for different practical matters. Many complex systems with modified circulation of paramagnetic ions have been studies thus far. During such modification different extraspheric ions can be selected. Sometimes this work results in interesting combinations of properties», - she explains.
Lately Anna has been studying new ferriferous complexes that contain ligands with branched structure. For this she uses Mossbauer spectroscopy based on resonant absorption and emission of gamma rays in solids.
«This method is convenient because of hyperfine interactions being very sensitive to spin transitions, local magnetic and structural heterogeneities. Information derived from gamma resonance can help fully describe the properties of studied objects under different external conditions», - says our interviewee. She has already presented some of her developments at international conferences on Mossbauer spectroscopy.
It's worth mentioning that physicists cooperate with the Department of Archeology and Ethnology in exploring the historical heritage of Volga Bulgaria. Mossbauer spectroscopy comes in handy when analyzing ceramic ware. This joint research has been published in the Bulletin of the Russian Academy of Sciences.
