Pyroelectric thermo-wave probing of BaZr0.2Ti0.8O3 ceramics
Nicholas V. Morozovsky, Yuriy O. Zagorodniy, Mykola Yelisieiev +10
BaxZr1-xTiO3 ceramics with 0.15 < x < 0.25, which have high dielectric permittivity, small leakage currents and low dissipation factor, are promising materials for tunable capacito…
Correlations of Spectroscopic and Dielectric Properties of Hafnia-Zirconia Nanoparticles
Yuriy O. Zagorodniy, Eugene A. Eliseev, Petr Jiricek +11
In this work we analyze correlations of X-ray photoelectron and diffraction spectra, and dielectric properties of hafnia-zirconia nanoparticles (the chemical compositions Hf0.4Zr0.…
A colossal dielectric response of Bi1-xSmxFeO3 nanopowders
Vladyslav O. Kolupaiev, Olexander S. Pylypchuk, Vladimir N. Poroshin +6
The dielectric permittivity of the pressed powder samples of Bi1-xSmxFeO3, with Sm content "x" varying in the range 0 - 0.2, has been investigated in the temperature range from 20…
Flexo-Strain Engineering of Phonons and Ferrons in Thin Films of Van der Waals Ferrielectrics
Anna N. Morozovska, Eugene A. Eliseev, Yujie Zhu +6
The influence of the flexoelectric coupling on the fluctuations of electric polarization and elastic strains can lead to the principal changes of the dispersion law of soft optical…
Composition-Driven Phase Evolution in Sm-Doped BiFeO3 via Latent-Field Reconstruction of Atomically Resolved STEM Data
Newsha Javanmardi, Christopher T. Nelson, Anna N. Morozovska +3
Functionalities of ferroelectric materials are governed by the spatial organization and coupling of polarization, strain, lattice rotation, and structural order accessible via atom…
Bilinear Flexo-Antiferrodistortive Coupling in Ferroelastics: Polar Twins, Antiphase Boundaries and Fingerprints of Alterelectricity
Eugene A. Eliseev, Anna N. Morozovska, Akash Saha +1
Using the Landau-Ginsburg-Devonshire approach we show that the linear gradient-type coupling between the electric polarization vector and antiferrodistortive long-range order param…
The Influence of Electric Field on the Anisotropic Dispersion of the Flexocoupling Induced Phonons and Ferrons in Van der Waals Ferrielectrics
Anna N. Morozovska, Eugene A. Eliseev, Yujie Zhu +4
As has been shown recently, the influence of the flexoelectric coupling (shortly "flexocoupling") on the fluctuations of electric polarization and elastic strains can lead to the p…
Hypothesis Learning in Automated Experiment: Application to Combinatorial Materials Libraries
Maxim Ziatdinov, Yongtao Liu, Anna N. Morozovska +4
Machine learning is rapidly becoming an integral part of experimental physical discovery via automated and high-throughput synthesis, and active experiments in scattering and elect…
The influence of elastic strain gradient on the upper limit of flexocoupling strength, spatially-modulated phases and soft phonon dispersion in ferroics
Anna N. Morozovska, Christian M. Scherbakov, Yulian M. Vysochanskii
Within the framework of Landau-Ginzburg-Devonshire (LGD) theory we studied the role of the flexocoupling between the order parameter and elastic strain gradients in the stability o…

N. V. Morozovsky, A. V. Semchenko, V. V. Sidsky +4
The effect of changes of the Nb content and annealing on charge vs. voltage and current vs. voltage characteristics of SrBi2(Ta,Nb)2O9 film was studied theoretically and experiment…
Could the Vegard strains govern extrinsic size effects in nanoparticles?
A. N. Morozovska, I. S. Golovina, S. V. Lemishko +3
