Origin of relaxor behavior in barium-titanate based lead-free perovskites
Vignaswaran Veerapandiyan, Maxim N. Popov, Florian Mayer +12
It is well known that disordered relaxor ferroelectrics exhibit local polar correlations. The origin of localized fields that disrupt long range polar order for different substitut…
Ferroelectric to incommensurate fluctuations crossover in PbHfO3-PbSnO3
Maria A. Kniazeva, Alexander E. Ganzha, Irena Jankowska-Sumara +6
Perovskite solid solutions PbHfO3-PbSnO3 offer valuable opportunities for studying the formation mechsnisms of incommensurate phases, owing to the presence of an intermediate (betw…
Subterahertz collective dynamics of polar vortices
Qian Li, Vladimir A. Stoica, Marek Paściak +29
The collective dynamics of topological structures have been of great interest from both fundamental and applied perspectives. For example, the studies of dynamical properties of ma…
Dynamic Displacement Disorder of Cubic BaTiO
M. Paściak, T. R. Welberry, J. Kulda +2
The three dimensional distribution of the X-ray diffuse scattering intensity of BaTiO has been recorded in a synchrotron experiment and simultaneously computed using molecular…
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…
Size and Time Rescaling at the Paraelectric to Ferroelectric Phase Transition in BaTiO
Marek Pasciak, Salah Eddine Boulfelfel, Stefano Leoni
We describe length and time rescaling across the paraelectric to ferroelectric phase transition in BaTiO. Small ferroelectric clusters are unable to grow in the paraelectric ph…
