Structural transition on Pb1−xSrxTiO3 produced by chemical method

Microstructure and antiferroelectric-like behavior of PbxSr1−xTiO3 ceramics

“…Recently, the hysteresis loops of lead-ferroelectric materials, including Pb(Zr, * Corresponding author. [14][15][16][17][18][19][20][21][22][23][24][25]. Moreover, the antiferroelectric-like or double hysteresis loops behavior is observed [19][20][21][22][23][24][25].…”

“…Over the past few years, some preliminary results on the microstructure and dielectric properties of PST ceramics and thin films were reported [14][15][16][17][18]. Among these properties, the polarization-electric field (P-E) relation is very interesting.…”

The phase evolution with temperature in 0.94PbZrO3–0.06Pb(Mg1/2W1/2)O3 antiferroelectric ceramic

“…These materials are suitable for nonlinear charge storage capacitors because a field-forced ferroelectric state releases all polarized charges and can therefore supply very high instantaneous currents at the ferroelectric to antiferroelectric reverse phase transition. Recently, AFE materials, including Pb(Zr,Ti)O 3 , (Pb,Ba)ZrO 3 , (Pb,Sr)TiO 3 , (Pb,La)(Zr,Ti)O 3 , NaNbO 3, and (Bi 0.5 Na 0.5 )TiO 3 systems, have attracted increasing scientific attention [3][4][5][6][7][8][9]. Among them, lead zirconate (PbZrO 3 ; PZ) and PbZrO 3 -based are the most attractive AFE materials, due to their high longitudinal strain response, and the latter is a proto-type of AFE ceramics that belongs to an ABO 3 -type perovskite family of oxides [10,11].…”

“…It is well known that the AFE to FE phase transformation in PZ ceramic requires a very strong electric field; otherwise, dielectric breakdown occurs. Consequently, most commercial AFE ceramics are chemically modified by adding Ba 2+ , Sr 2+ , Ti 4+ or Sn 4+ to reduce the critical field and optimize the physical and electrical properties [3][4][5][6][7][8][9]. Sawaguchi [15] studied the effect of Ti 4+ substitution in PZ on temperature variation of the P-E hysteresis loop and established the ferroelectric intermediate phase between the AFE and PE phase.…”

Phase-separation-induced self-assembly of controllable PbTiO3 nanodots on Si substrates

“…Although sol-gel preparation of PT has been intensively studied [26][27][28][29][30], most of them focused on the phase purity and some other properties. In our previous work, a sol-gel based phaseseparation-induced self-assembly (PSIA) route was proven to be effective in direct preparation of TiO 2 nanodots on substrates with controlled nanodot size and density [31,32].…”
