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…
Resistive switching and charge accumulation in Hf0.5Zr0.5O2 nanoparticles
Oleksandr S. Pylypchuk, Ihor V. Fesych, Victor V. Vainberg +13
We revealed the resistive switching, negative differential resistance and charge accumulation effects in Hf0.5Zr0.5O2 nanopowders sintered by the auto-combustion sol-gel method and…
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…
