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…
