Comportamento térmico do PbTiO3 modificado por terras raras Thermal behavior of rare earth modified PbTiO3

Cerâmica, 2005
Titanatos de chumbo dopados com itérbio e ítrio, PYbT e PYT foram preparados pelo método Pechini. Os materiais obtidos foram calcinados sobre fluxo de oxigênio em diferentes temperaturas e investigados utilizando-se as técnicas de difração de raios X ...

Optimization of electro-strain and ferroelectric properties of P(VDF-TrFE) films under the synergistic effect of PTO nanosheets and in-situ electrostatic field

Journal of Materiomics
Traditional ferroelectric materials, such as lead zirconate titanate (PZT) ceramics, exhibit positive strain when subjected to an electric field along the polarization direction.

Super-Lattice Structure and Phase Evolution of Pb(Lu0.5Nb0.5)O3-PbTiO3 Single Crystal with Low PbTiO3

Crystals, 2018
The phase diagram of the Pb(Lu0.5Nb0.5)O3-PbTiO3 (PLN-PT) binary system was previously reported based on XRD and dielectric measurements results. Unusually, the Curie temperature of PLN-PT with low PT obtained from the phase diagram is much lower than ...

Electrocaloric effects in ferroelectrics and multiferroics from first principles

Journal of Materiomics
The electrocaloric (EC) effect characterizes the change in temperature or entropy of a material under the application of an external electric field. Ferroelectric and multiferroic materials have attracted considerable interest due to their potential for ...

Electrical de-poling and re-poling of relaxor-PbTiO3 piezoelectric single crystals without heat treatment

Nature Communications
Re-poling of unexpected partially depoled piezoelectric materials conventionally needs to be first fully depoled through annealing above their Curie temperature to revive piezoelectric performances. Here, we investigated de-poling and re-poling of Pb(In1/
