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…
Magnetic properties and charge transport mechanisms in oxygen-deficient HfxZr1-xO2-y nanoparticles
Oleksandr S. Pylypchuk, Eugene A. Eliseev, Andrii V. Bodnaruk +12
Study of nanoscale hafnia-zirconia physical properties is the key topic in fundamental and applied science. However, charge transport mechanisms and magnetic properties of hafnia-z…
Coexistence of Ferroelectric and Relaxor-like Phases in a Multiferroic Solid Solution (1-x)Pb(FeNb)O-xPbMnO
Anna N. Morozovska, Victor N. Pavlikov, Yuriy O. Zagorodniy +7
Experimental and theoretical studies of unusual polar, dielectric and magnetic properties of room temperature multiferroics, such as perovskites Pb(FeNb)O (PFN)…
Colossal dielectric response of HfxZr1-xO2 nanoparticles
Oleksandr S. Pylypchuk, Victor V. Vainberg, Vladimir N. Poroshin +10
We reveal a colossal dielectric response of small (5 - 10 nm) oxygen-deficient HfxZr1-xO2 nanoparticles (x = 1 - 0.4), prepared by the solid-state organonitrate synthesis. The effe…
The origin of the ferroelectric-like orthorhombic phase in oxygen-deficient HfO2-y nanoparticles
Eugene A. Eliseev, Iryna V. Kondakova, Yuri O. Zagorodniy +6
In this work we established the relationship between the crystalline structure symmetry, point defects and possible appearance of the ferroelectric-like polarization in HfO2-y nano…
