Dielectric spectroscopy of solid solutions based on sodium–potassium–cadmium in the temperature range (10 ÷ 900) K
M. O. Moysa, K. P. Andryushin, A. V. Pavlenko, S. P. Kubrin, and L. A. Reznichenko
This paper studies the dielectric spectra of solid solutions (SS) of the system (1 − x − y)NaNbO3–xKNbO3 –yCdNb2O6y= 0.075, x= 0.05 ÷ 0.30 in the temperature range (10 ÷ 900) K. The formation of a local maximum was established in the interval (260 ÷ 300) K at small x values, which, as KNbO3 increases, is

Phase-field study of crystallographic texturing in piezoelectric polycrystals
Meixin Wang, Tian Xia, and Liwei D. Geng
Crystallographic texturing enables the design of piezoelectric polycrystals that outperform traditional random polycrystals by exhibiting outstanding piezoelectric properties. In this work, phase-field modeling and computer simulation were employed to study the effect of crystallographic texture on the piezoelectric pr

Performance enhancement of ultrasonic transducer made of textured PNN-PZT ceramic
Lang Bian, Ke Zhu, Qian Wang, Jinpeng Ma, Jinhui Fan, Xudong Qi, Guicheng Jiang, Bo Zhao, Rui Zhang, Bin Yang, and Wenwu Cao
In this paper, 0.36Pb(Ni1/3Nb2/3)O3–0.24PbZrO3–0.40PbTiO3(PNN-PZT) ceramic was prepared, and texture engineering was performed on this PNN-PZT ceramic to improve its electromechanical properties and temperature stability. Single element ultrasonic transducers were prepared using PNN-PZT, PNN-PZT textured ceramics, and

Peculiarities of the dependences of the dielectric properties of solid solutions of multicomponent systems on the electronegativity of their constituent cations
Andryushin Konstantin, Dudkina Svetlana, Shilkina Lidiya, Sahoo Sushrisangita, Moysa Maksim, Andryushina Inna, Verbenko Iliya, and Reznichenko Larisa
Solid solutions (SS) of 3- and 4-component systems based on lead titanate-zirconate were prepared by the method of solid-phase reactions and uniaxial hot pressing. The dependences of the relative permittivity of polarized samples on the electronegativity (EN) of their constituent cations have been studied. The ferro-ha

Hierarchical-vortex polarization domain pattern in nano polycrystalline ferroelectric
Zhiyong Huang, Qinan Li, Yin Liang, Xiaoqiao He, Jiagang Wu, Haidong Fan, and Xiaobao Tian
Domain pattern is the carrier of electromechanical property. A novel domain pattern will open a gate for ferroelectric nanodevice. A distinctive topological domain pattern termed as hierarchical vortex (Hvo) has been found in polycrystalline ferroelectric based on the first-principles-based atomistic method. The Hvo pa

The equation of state for metal-doped ferroelectrics within the Weiss model
Ivan A. Starkov, Mikhail A. Mishnev, and Alexander S. Starkov
This paper presents a theoretical model for describing the thermodynamic properties of doped ferroelectric crystals based on a modified Weiss mean-field approach. Accounting for quadrupole and octupole terms in the expression for the effective field within the Weiss model makes it possible to move from the Langevin equ

Effect of interface carbonization on dielectric properties of potassium nitrate nanocomposite based on porous glasses
A. Molokov, A. Sysoeva, A. Naberezhnov, R. Kumar, E. Koroleva, and S. Vakhrushev
Dielectric properties and structure of pure and carbon-modified nanocomposites on the base of porous glasses with an average pore diameter of 6 nm (PG6) with embedded KNO3 have been studied at the temperature diapason of 300–430 K and at frequencies of 0.1–3 × 106 Hz on cooling. X-ray diffraction studies of these
