Magnetodielectric effect and optic soft mode behaviour in quantum paraelectric EuTiO3 ceramics

S. Kamba, D. Nuzhnyy, P. Vanek +7

Infrared reflectivity and time-domain terahertz transmission spectra of EuTiO3 ceramics revealed a polar optic phonon at 6 - 300K, whose softening is fully responsible for the rece…
