The performance of complex oxide heterostructures depends primarily on the interfacial coupling of the two component structures. This interface character inherently varies with the synthesis method and conditions used since even small composition variations can alter the electronic, ferroelectric, or magnetic functional properties of the system. The focus of this article is placed on the interf...

To stabilise ferroelectric-tetragonal phase of BaTiO3, the double-doping of Bi and Mn up to 0.5 mol% was studied. Upon increasing the Bi content in BaTiO3:Mn:Bi, the tetragonal crystal-lattice-constants a and c shrank and elongated, respectively, resulting in an enhancement of tetragonal anisotropy, and the temperature-range of the ferroelectric tetragonal phase expanded. X-ray absorption fine ...

A key obstacle to the development of high-capacity three-dimensional information mass storage systems using photorefractive crystals is that readout of holograms stored in the conventional manner is destructive. Thus hologram fixing in these materials is important if practical systems are to be built. High-temperature (801200C) photorefractive grating writing results for a variety of pure and d...

We experimentally and theoretically investigate the effects of utilizing BaTiO3 nanoparticles as additives in polythiophene/fullerene solar cells. BaTiO3 nanoparticles were chosen because of their multifaceted potential for increasing exciton dissociation (due to their high dielectric constant) and light scattering. To achieve stable suspensions for device fabrication, the nanoparticles were fu...

We present a study of the control electric field induced strain on magnetic and electrical transport properties in magneto-elastically coupled artificial multiferroic Fe3O4/BaTiO3 heterostructure. In this heterostructure, Fe3O4 thin film is epitaxially grown form bilateral domains, analogous to a-c stripe domains underlying BaTiO3(001) substrate. By in-situ dependent magnetization measurements,...

One of the most desirable attributes non-volatile memories and memristors is a fast non-destructive read out their resistive state. Prototypical ferroelectric (FE) use bulk photovoltaic response associated to polarization FE films address this requirement by optically sensing binary memory cells. A more advanced type tunnel junctions (FTJs). They feature state ratios RHigh/RLow up 106, with con...

We report on the coupling between ferroelectric and magnetic order parameters in a nanostructured BaTiO3-CoFe2O4 ferroelectromagnet. This facilitates the interconversion of energies stored in electric and magnetic fields and plays an important role in many devices, including transducers, field sensors, etc. Such nanostructures were deposited on single-crystal SrTiO3 (001) substrates by pulsed l...

A maximal product of stiffness and viscoelastic damping (E tan d), a figure of merit for damping layers, is desirable for structural damping applications. Particulate-reinforced metal–matrix composites were prepared by ultrasonic agitation of the melt and composed of the zinc–aluminum (ZnAl) alloy Zn80Al20 (in wt%) as the lossy matrix and SiC or BaTiO3 as the particulate reinforcements. ZnAl–Si...

We present a systematic evaluation of the effects of polarization switchability on surface structure and stoichiometry in BaTiO3 and PbTiO3 ferroelectric oxides. We show that charge passivation, mostly by ionic surface reconstructions, is the driving force for the stability of the surfaces, which suggests that varying the substrate polarization offers a new mechanism for controlling surface rec...

The effect of poly(acrylic acid) (PAA), poly(vinylpyrrolidone) (PVP), sodium dodecylsulfate (SDS), hydroxypropylmethylcellulose (HPMC), and D-fructose additives on the growth of BaTiO3 particles by aqueous synthesis is studied. Through different mechanisms, all the tested additives influenced the growth of BaTiO3. For high concentrations, PAA adsorbed on specific crystallographic faces changing...
