Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
Broad-band dielectric response of BTZ-BCT piezoceramics: soft and central mode behaviour
S. Kamba, E. Simon, V. Skoromets +6
Dielectric properties of BTZ-BCT ceramics were probed in the frequency range from 10 Hz to 100 THz in a broad temperature range (10-900 K). Polar soft phonon observed in infrared s…
Electromagnon in the Z-type hexaferrite
Filip Kadlec, Christelle Kadlec, Jakub Vit +12
We studied experimentally the high-temperature magnetoelectric prepared as ceramics (x = 0, 0.2) and a single crystal (x = 0.5…
Possible coupling between magnons and phonons in multiferroic CaMn7O12
Filip Kadlec, Veronica Goian, Christelle Kadlec +7
Spin and lattice dynamics of CaMn7O12 ceramics were investigated using infrared, THz and inelastic neutron scattering (INS) spectroscopies in the temperature range 2 to 590 K, and,…
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…
