Sonochemical synthesis is used to produce ceramic-based nanocomposites with ferromagnetic nanoparticles as active elements.

- In the case of superconductors, nanoparticles play role of efficient pinning centers. The main focus of the project is to understand the behavior of magnetic nanoparticles embedded into the bulk of a superconductor and their interaction with vortices.
- In case of refractory ceramics, the use of nanoparticles result in superparamagnetic behavior. We study frequency response of such systems in a wide range of chemical, structural and physical parameters.
