Electronic and crystalline structure of perovskite crystals: A case of SrRuO3
Abstract
Perovskite crystals have attracted the curiosity of scientific community due to the enormous variety of complex phenomena – from ferroelectricity, ferromagnetism, and piezoelectricity up to insulator-to-metal transition, colossal magnetoresistance, and superconductivity – arising from the subtle coupling between structural, electronic, and magnetic degrees of freedom. Therefore, it is not surprising that they have already found numerous applications in such technological areas as electrochemistry, heterogeneous catalysis, and modern solid-sate electronics. Among a diverse family of perovskites, SrRuO3 is well known for its outstanding electrical, magnetic, and thermal properties, high resistant to chemical solutions, and low lattice mismatch with plenty of functional oxides. In this talk, I will present the results that we have obtained during my PhD and post-PhD years at Vilnius University trying to explain and supplement experimental findings on electronic and crystalline structure of SrRuO3.

Magnetic properties of nanodiamonds: Theoretical investigation
Abstract
Nanodiamonds (NDs) belong to a family of carbon-based nanomaterials that recently gained a lot of attention in such nanomedical areas as tissue engineering, labelling, quantum sensing, and drug delivery. Concerning the latter, a combination with the bioimaging capabilities could make NDs a very promising platform for the clinical theranostic applications, thereby allowing a more effective exploitation of these nanoparticles. In order to fully utilize the bioimaging potential of NDs using such techniques as magnetic resonance imaging, which in turn require a paramagnetic reservoir to be present in the system, one has to be aware of their magnetic properties. In this talk, I will present the theoretical results that were obtained during my postdoctoral studies and afterwards at Vilnius University trying to broaden the knowledge about the magnetic properties of NDs, in particular the electronic g-tensor.
