Extended study of crystal structures, optical properties and vibrational spectra of polar 2-aminopyrimidinium hydrogen phosphite and bis(2-aminopyrimidinium) sulfate monohydrate and two 2-aminopyrimidinium hydrogen sulfate polymorphs
Irena Matulkova, Ladislav Bohaty, Petra Becker +6
This study aimed primarily at completing and extending the characterization of the crystallographic, spectroscopic and optical properties of polar, biaxial, optically negative 2-am…
Unusual ferroelectric and magnetic phases in multiferroic 2H-BaMnO ceramics
Stanislav Kamba, Dmitry Nuzhnyy, Maxim Savinov +16
The structural phase transition in hexagonal BaMnO occurring at =130 K was studied in ceramic samples using electron and X-ray diffraction, second harmonic generation as w…
No clear evidence of ferroelectric order in tensile-strained anatase-TiO2 thin films grown on (110) NdGaO3 substrates
Stella Skiadopoulou, Stanislav Kamba, Jan Drahokoupil +4
Very recently there was a report of the discovery using piezoelectric force microscopy (PFM) of a switchable ferroelectric polarization in 1.6 % tensile strained TiO2 thin film wit…
Multiple soft-mode vibrations of lead zirconate
J. Hlinka, T. Ostapchuk, E. Buixaderas +7
Polarized Raman, IR and time-domain THz spectroscopy of orthorhombic lead zirconate single crystals yielded a comprehensive picture of temperature-dependent quasiharmonic frequenci…
Grain Size Influence on Dynamics of Polar Nanoclusters in PMN-35%PT Ceramics: Broadband Dielectric and Infrared Spectra
V. Bovtun, S. Kamba, S. Veljko +9
Dielectric response e*(f,T) and polar phonon spectra of coarse grain (grain size ~ 4 mkm) and fine grain (grain size ~ 150 nm) ceramics of PbMg_(1/3)Nb_(2/3)O3-35%PbTiO3 were inves…
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…
