High-Entropy Oxides Based on Valence Combinations: Design and Practice
Lei Tang, Zemin Li, Kepi Chen +3
High-entropy oxides (HEOs) are a new class of materials that are promising for a wide range of applications. Designing HEOs needs to consider both geometric compatibility and elect…
Ferroelectricity in Pb(ZrTi)O thin films: critical thickness and 180 stripe domains
Zhongqing Wu, Ningdong Huang, Zhirong Liu +4
The ferroelectric properties of disorder Pb(ZrTi)O thin films are investigated with Monte Carlo simulations on the basis of a first-principles-derived Hamiton…
Huge enhancement of electronmechanical responses in compositionally modulated PZT
Ningdong Huang, Zhirong Liu, Zhongqing Wu +4
Monte Carlo simulations based on a first-principles-derived Hamiltonian are conducted to study the properties of PZT alloys compositionally modulated along the [100] pseudocubic di…
Electric-field-induced phase transition of <001> oriented Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals
Ke-Pi Chen, Xiao-Wen Zhang, Hao-Su Luo
<001> oriented 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 single crystals were poled under different electric fields, i.e. Epoling=4 kV/cm and Epoling=13 kV/cm. In addition to the temperature-d…
Stochastic resonance induced by random fields in ferroelectrics
Zhi-Rong Liu, Wenhui Duan, Bing-Lin Gu +1
We propose a mechanism of stochastic resonance induced by spatial noise (electric random fields) in ferroelectrics. The calculations demonstrate the characteristic of the stochasti…
Proportion of frozen local polarization in relaxor ferroelectrics
Zhi-Rong Liu, Yong Zhang, Bing-Lin Gu +1
A Landau-type phenomenological cluster theory was presented to model the freezing process of local polarization in relaxors. Based on the theory, the proportion of frozen polarizat…
Eight-potential-well order-disorder ferroelectric model and effects of random fields
Zhi-Rong Liu, Bing-Lin Gu, Xiao-Wen Zhang
An eight-potential-well order-disorder ferroelectric model was presented and the phase transition was studied under the mean-field approximation. It was shown that the two-body int…
Effects of ac-field amplitude on the dielectric susceptibility of relaxors
Zhi-Rong Liu, Bing-Lin Gu, Xiao-Wen Zhang
The thermally activated flips of the local spontaneous polarization in relaxors were simulated to investigate the effects of the applied-ac-field amplitude on the dielectric suscep…
CVM studies on the atomic ordering in complex perovskite alloys
Zhi-Rong Liu, Jian-She Liu, Bing-Lin Gu +1
The atomic ordering in complex perovskite alloys is investigated by the cluster variation method (CVM). For the 1/3\{111\}-type ordered structure, the order-disorder phase transiti…
Dielectric nonlinearity of relaxor ferroelectric ceramics at low ac drives
Xiao-Wen Zhang, Xi Liu, Zhi-Rong Liu +1
Dielectric nonlinear response of (PbMgNbO)(PbTiO) (0.9PMN-0.1PT) relaxor ceramics was investigated under different ac drive voltages. It was…
