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…
Role of Oxygen Vacancies in Stabilizing the Orthorhombic Phases of Hf0.5Zr0.5O2 Nanoparticles
Yuriy O. Zagorodniy, Eugene A. Eliseev, Valentin V. Laguta +13
In this work we study the stabilization of the orthorhombic phases in small Hf0.5Zr0.5O2 nanoparticles (average size ~ 7 nm) annealed under different oxygen partial pressures. Conc…
Correlations Between the Dielectric Properties, Domain Structure Morphology and Phase State of Bi1-xSmxFeO3 Nanoparticles
Oleksandr S. Pylypchuk, Vladyslav O. Kolupaiev, Victor V. Vainberg +5
Nanoscale multiferroics are basic model objects for studying polar, magnetic and magnetoelectric properties and mutual couplings. Bismuth-samarium ferrite (Bi1-xSmxFeO3) is a model…
Electric Charge Transport and Dielectric Properties of the Barium Titanate Ceramics Obtained by Spark-Plasma Sintering with Different Carbon Content
Oleksandr S. Pylypchuk, Victor V. Vainberg, Denis O. Stetsenko +9
Barium titanate (BaTiO3) ceramics with a different content of carbon were synthesized by spark-plasma sintering (SPS) at the temperature of 1100 C in vacuum under pressure. The con…
