Original language name
Magnetodielectric effect and optic soft mode behaviour in quantum paraelectric EuTiO3 ceramics
Original language description
Infrared reflectivity and time-domain terahertz transmission spectra of EuTiO3 ceramics revealed a polar optic phonon at 6?300 K whose softening is fully responsible for the recently observed quantum paraelectric behaviour. Even if our EuTiO3 ceramics show lower permittivity than the single crystal due to a reduced density and/or small amount of secondary pyrochlore Eu2Ti2O7 phase, we confirmed a magnetic field dependence of the permittivity, also slightly smaller than in single crystal.

Magnetodielektrický efekt a chování měkkého módu v kvantově paraelektrické EuTiO3 keramice
Czech description
Infračervená a THz spektroskopie ukázala, že měkký polární fonon je zcela odpovědný za nedávno objevené kvantově paraelektrické chování EuTiO3. Zároveň jsme pozorovali výraznou změnu permitivity s magnetickým polem (=magnetodielektrický jev), změna frekvence měkkého módu s mag. polem však nebyla pozorována.
