Phase transition between two different orientations of the Q phase in the NaNbO thin film
A. V. Pavlenko, D. V. Stryukov, M. V. Vladimirov +8
Temperature evolution of dielectric response, atomic structure, and lattice dynamics in thin film of sodium niobate in the epitaxial NaNbO/SrRuO/(001)MgO heterostructure is…
Magnetoelectric effect in antiferromagnetic multiferroic Pb(Fe1/2Nb1/2)O3 and its solid solutions with PbTiO3
V. V. Laguta, V. A. Stephanovich, I. P. Raevski +4
Antiferromagnets (AFMs) are presently considered as promising materials for applications in spintronics and random access memories due to the robustness of information stored in AF…
Room-temperature paramagnetoelectric effect in magnetoelectric multiferroics Pb(Fe1/2Nb1/2)O3 and its solid solution with PbTiO3
V. V. Laguta, A. N. Morozovska, E. A. Eliseev +5
We have observed the magnetoelectric response at room temperature and above in high-resistive ceramics made of multiferroic Pb(Fe1/2Nb1/2)O3 (PFN) and PFN-based solid solution 0.91…
Condensation of the atomic relaxation vibrations in lead-magnesium-niobate at
Sergey Prosandeev, Igor P. Raevski, Maria A. Malitskaya +4
We present neutron diffraction, dielectric permittivity and photoconductivity measurements, evidencing that lead-magnesium niobate experiences a diffuse phase transformation betwee…
Bias field effect on the temperature anomalies of dielectric permittivity in PbMg1/3Nb2/3O3- PbTiO3 single crystals
I. P. Raevski, S. A. Prosandeev, A. S. Emelyanov +8
In contrast to ordinary ferroelectrics where the temperature, Tm, of the permittivity maximum monotonically increases with bias field, E, in (1-x)PbMg1/3Nb2/3O3-(x)PbTiO3 (0<x<0.35…
Experimental and theoretical study of the influence of disorder on diffuse first-order phase transitions: NaNbO3: Gd and KTaO3: Li as examples
M. S. Prosandeeva, S. I. Rayevskaya, S. A. Prosandeev +2
We consider consequences of local disorder in systems experiencing first order phase transitions. Such systems can be of rather different nature. For example, manganates showing gi…
