Giant dielectric permittivity in Nb-doped rutile crystals
D. Nuzhnyy, V. Bovtun, J. Petzelt +13
Dielectric properties of Nb-doped (~1.5 at%) rutile single crystals were studied in the 10-300 K temperature range (at frequencies below the MHz range down to 0.3 K) in a broad fre…
Infrared, terahertz, and microwave spectroscopy of the soft and central modes in Pb(Mg1/3Nb2/3)O3
D. Nuzhnyy, J. Petzelt, V. Bovtun +4
From the new infrared (IR) reflectivity and time-domain terahertz (THz) spectra combined with available high-frequency dielectric data above the MHz range in a broad temperature ra…
Far infrared and terahertz spectroscopy of ferroelectric soft modes in thin films: A review
Jan Petzelt, Stanislav Kamba
Far-infrared and terahertz spectroscopy of ferroelectric soft and central modes in thin films on substrates is reviewed. In addition to classical displacive proper ferroelectrics,…
Peculiar Bi-ion dynamics in Na1/2Bi1/2TiO3 from terahertz and microwave dielectric spectroscopy
Jan Petzelt, Dmitry Nuzhnyy, Viktor Bovtun +6
Dynamics of the main dielectric anomaly in Na1/2Bi1/2TiO3 (NBT) was studied by time-domain THz and microwave spectroscopy, using also previously published data and their new overal…
Broadband dielectric spectroscopy of Ba(Zr,Ti)O3: dynamics of relaxors and diffuse ferroelectrics
J. Petzelt, D. Nuzhnyy, M. Savinov +6
Broadband dielectric spectroscopy from Hz up to the infrared (IR) range and temperature interval 10-300 K was carried out for xBaZrO3-(1-x)BaTiO3 (BZT-x, x = 0.6, 0.7, 0.8) solid s…
Magnetodielectric coupling and phonon properties of compressively strained EuTiO3 thin films deposited on LSAT
S. Kamba, V. Goian, M. Orlita +13
Compressively strained epitaxial (001) EuTiO3 thin films of tetragonal symmetry have been deposited on (001) (LaAlO3)_0.29-(SrAl_{1/2}Ta_{1/2}O3)_0.71 (LSAT) substrates by reactive…
