Mobile oxygen vacancies are increasingly widely believed to be responsible for electrical conductivity in perovskite oxide ferroelectrics. Here, this hypothesis is debated. The small-signal conductivity is investigated in oxygen-deficient films of ba

In perovskite oxide ferroelectrics, gradients of lattice strain are known to induce nanoscale topological structures, leading to novel or enhanced functionality. Here, we experimentally detect and theoretically analyze thickness distribution of struc

Enhancement of electrical conductivity in fundamentally insulating ABO₃ perovskite oxide ferroelectrics is crucial for innovative applications in resistive switching, photovoltaics, and catalysis. One of the methods to raise conductivity in bulk cr

Diverse effects of lattice strain on the optical properties in the near-infrared to vacuum ultraviolet spectral range are experimentally revealed in cube-on-cube-type epitaxial perovskite SrTiO3 films grown on compressive substrate. Compared to the r

The electrical conductivity of epitaxial BaTiO₃ films was studied by small-signal impedance spectroscopy at temperatures of 10–720 K using Pt-BaTiO₃ — SrRuO₃ capacitors. The ∼150-nm-thick BaTiO₃ films possessed different lattice strains

The existence of out-of-plane-oriented oxygen vacancy dipoles was experimentally established in (001) perovskite epitaxial films of ferroelectric barium titanate by analyses of the crystal and electronic structure as well as the ferroelectric and opt

Misfit strains arising from a film–substrate mismatch can induce novel phases and properties in the epitaxial films of perovskite oxides. Here we employ yet another effect, namely, strain-assisted formation of oxygen vacancies. We demonstrate the m

A significant increase in conductivity under an applied magnetic field or large negative magnetoresistance up to several percent is observed at low temperatures in epitaxial perovskite NdNiO₃ films. The (20–100 nm) strained films are grown on com

In relaxor ferroelectrics, the interplay between the short-range-order dipolar state and long-range-order ferroelectric state leads to outstanding response functions, which enable valuable capacitor, electromechanical, pyroelectric, and electrocalori

Magneto-dielectric properties of (A²⁺)MnO₃-type perovskites are attractive for applications and stimulate extensive studies of these materials. Here, the complex dielectric and magnetic responses are investigated as in epitaxial films of SrTi₀
