We focus on the study of dielectric and vibration spectra of ferroelectrics and multiferroics in the form of single crystals, ceramics, thin films and multilayers in a very broad spectral and temperature range (1 mHz – 150 THz, 5 – 950 K).

What is original and unique in our lab?

• We developed unique experimental methods for dielectric measurements of high-permittivity and high-loss ferroelectric materials (bulk and thin films) in the microwave range from 10 to 400 K.

• Microwave magnetic permeability can be measured up to 3 GHz between 100 and 400 K.

• Far-infrared dielectric response can be obtained not only on bulk samples but also on ultra-thin films with thickness down to 10 nm. Temperature range 5 – 900 K.

• Time domain THz transmission spectra (0.1-2.4 THz) can be measured between 5 and 900 K, THz reflectance below 300 K. A new recent acquisition allows us to measure the THz transmission spectra in a magnetic field up to 7 T (temperatures 1.5 to 300 K). All this in collaboration with the THz spectroscopy group.

• In collaboration with other groups from our Institute we can study magnetoelectric and magnetic properties of multiferroics using PPMS14 and SQUID Magnetometers from Quantum Design.
