The ultrafast photoinduced strain (UPS) resulting from the coupling of piezoelectric and photovoltaic effects in ferroelectric has been focused last decade, endowing them with extensive applications including optical memories, sensors actuators engineering. mechanism screening depolarization field by carriers is generally accepted for UPS ferroelectrics, while thermal component usually diluted ...

The evolution of the crystal structure (1-x) PbFe2 / 3W1 3O3 - хPbTiO3 solid solutions depending on PbTiO3concentrations (at x = 0.25, 0.3, 0.35) in region morphotropic phase boundary was studied using x-ray diffraction at room temperature. It established that all three compositions are a mixture cubic and tetragonal phases, an increase concentration PbTiO3 above 30 mol. % leads to contribution...

Spin-polarized two-dimensional electron gas (2DEG) at oxide interfaces is an emerging physical phenomenon, which technologically important for potential device applications. However, most previous relevant studies only focused on the creation and characterization of spin-polarized 2DEG. To push forward applications, control 2DEG by electric field step. Here, a model system based antiferromagnet...
