The activity of our group concentrates on low temperature (down to 0.3K) studies:

• Dielectric investigation of the coexistence of paraelectric/proton- glass and ferroelectric(antiferroelectric) order in proton glass system Rb_1-x(NH4)_xH₂AsO₄ (RADA).
• EPR and dielectric study of nominally pure and doped incipient ferroelectric KTaO₃.
• Thermal conductivity of ferroic crystals in the temperature range from 0.3K to 300K.
• Phase transitions and low temperature properties of fullerides: solid C₆₀ and C₇₀ and thin films of C₆₀ and C₇₀, studied by Electron Paramagnetric Resonance and dielectric methods.
• EPR of fullerene ions and superconductivity in potassium and rubidium intercalated fullerenes.

• SE/X Electron Paramagnetic Resonance Spectrometer,
• Helium 3 cryostat ( 0.3K to 300K ),
• Superconducting Magnet,
