Central mode and soft mode behavior in PbMg1/Nb2/3O3 relaxor ferroelectric
S. Kamba, M. Kempa, V. Bovtun +3
The relaxor ferroelectric PbMg1/Nb2/3O3 was investigated by means of broad-band dielectric and Fourier Transform Infrared (FTIR) transmission spectroscopy in the frequency range fr…
High-temperature phase transitions in SrBi_2Ta_2O_9 film: a study by THz spectroscopy
F. Kadlec, S. Kamba, P. Kuzel +3
Time-domain THz transmission experiment was performed on a film deposited on sapphire substrate. Temperatures between 300 and 923 K were investigated and comple…
Dielectric spectra of a new relaxor ferroelectric system Ba2LnTi2Nb3O15 (Ln=La, Nd)
S. Kamba, S. Veljko, M. Kempa +7
New relaxor ferroelectric system has been synthesized. BLTN exhibits a smeared maximum of permittivity, characteristic of classic relaxor behaviour, with a peak shift from 185 K at…
Lattice Dynamics in PMN
S. A. Prosandeev, E. Cockayne, B. P. Burton +5
Lattice dynamics for five ordered PMN supercells were calculated from first principles by the frozen phonon method. Maximal symmetries of all supercells are reduced by structural i…
Temperature dependence of microwave and THz dielectric response in Srn+1TinO3n+1 (n=1-4)
D. Noujni, S. Kamba, A. Pashkin +6
The microwave, near-millimetre and infrared (IR) dielectric response of Srn+1TinO3n+1 (n=1-4) Ruddlesden-Popper homologous series was studied in the temperature range 10 to 300 K.…
