“…14 For PbTiO 3 , a detailed study of the influence of particle size on ferroelectricity has been performed 15 and differential scanning calorimetric and dielectric measurements indicated that the phase transition temperature decreases when the particle size diminishes. A similar behaviour was found by Kanata et al, 16 who showed that in nanoparticles of BaTiO 3 (grain size <20 µm) the ferroelectric phase transition temperature decreases with decreasing particle size. Also, Yamamoto et al 22 observed a phase transformation in BaTiO 3 at room temperature while only changing particle size of the powder.…”

“…3. With decreasing film thickness, the mean polarization decreases, while the mean susceptibility increases, then goes up rapidly accompanying with a dielectric divergence, which is in agreement with the experimental data of KDP [34], BaTiO 3 [35] and PbTiO 3 fine particles [36,37]. For ferroelectric thin films, when the thickness is smaller than the critical value, the polarization cannot line up under thermoequilibrium because of the weakened long-range interaction by the sample size, but when a weak electric field is applied, they line up easily and show a large dielectric susceptibility.…”

“…Earlier literature (Buessem et al 1966;Bell et al 1984;Arlt et al 1985;Arlt 1987;Kanata et al 1987;Dutta and Gregg 1992) reported that to stabilize tetragonal BaTiO 3 , it is important that crystal size should exceed 1 μm to accommodate the strains caused by the transformation from cubic to tetragonal structure. Few successful cases of tetragonal BaTiO 3 powder synthesis below 100 nm size have been reported recently (Lu et al 2000;Zhang et al 2001;Xu and Gao 2003;Kwon et al 2006).…”
