Dielectric Properties of (111) and (100) Lead-Zirconate-Titanate Films Prepared by Sol-Gel Technique

Abstract

The response to an AC magnetic field of a type I1 superconducting single-crystal Pb-Na cylindrical rod has been observed as a function of longitudinal DC fields. The results show two different regimes of flux pinning within the specimen. At low fields in the mixed state the specimen is largely reversible in the bulk and all pinning appears to be at the surface. In a field close to H,,, there is a peak region where bulk pinning rapidly dominates. Evidence for these regimes is discussed.

Effects of Heating Profiles on the Orientation and Dielectric Properties of 0.5Pb(Mg1/3Nb2/3)O3‐0.5PbTiO3 Thin Films by Chemical Solution Deposition

“…These results implied that the P s direction of the (111) crystalline orientation in the film was (111). This was consistent with the polarization behavior of (100)-and (111)-preferred PZT films reported by Aoki et al 5 Figure 7 shows the dc bias dependency of dielectric constant of the D2 and S2 films measured at 100 kHz and an oscillation voltage of 10 mV. Figure 7 shows that the dc bias dependency of the (100)-preferred film was weaker than that of the (111)-preferred film.…”

“…4 The dielectric properties of PMN-PT films, including dielectric constant, remanent polarization, coercive field, and fatigue behavior, are sensitive to the relative crystallographic orientation. 5,6 Recently, several researchers have investigated the synthesis, processing, and dielectric properties of PMN and PMN-PT thin films. [7][8][9][10] However, few studies have been conducted on the development of crystallographic texture and microstructure of the PMN-based thin films prepared by sol-gel processing.…”

Growth and electrical properties of Pb(Zr,Ti)O3 thin films by a chemical solution deposition method using zirconyl heptanoate as zirconium source

“…It has been confirmed that electrical properties of PZT thin films are strongly dependent on orientation of thin films, much effort has been made to control the orientation [12,20,21]. In our study, by using different substrates and selecting different processing parameters, the PZT thin films with different preferential orientations were obtained.…”

Structure and piezoelectric properties of sol–gel-derived (001)-oriented Pb[Yb1/2Nb1/2]O3–PbTiO3 thin films

“…Ishikawa et al 19 have reported that the use of a PT seeding layer reduces the nucleation temperature of perovskite films and changes their texture development. Aoki et al 20 also reported that the crystalline orientation of each PZT layer was controlled by optimizing the temperatures of intermediate heat treatments. From Figs.…”
