Abstract: Superlattice-structured epitaxial thin films composed of Mn(5%)-doped BiFeO3 and BaTiO3 with a total thickness of 600 perovskite (ABO3) unit cells were grown on single-crystal SrTiO3 sub- strates by pulsed laser deposition, and their polarization and dielectric properties were ...
The single phase perovskite was found at calcination temperature of 900 degrees C for 6h. The effects of K doping on the crystal structure, microstructure, magnetic and electrical properties of lead-free 0.7BiFeO(3-)0.3BaTiO(3) ceramics were investigated and discussed. The fracture micrographs of...

The films fabricated on single-crystal perovskite substrates of (100)SrRuO3//(100)SrTiO3 and (111)SrRuO3//(111)SrTiO3 exhibited preferential (100)(pc) and (111)(pc) orientations, respectively, depending on the crystallographic feature on the substrate surface. Excess Bi addition into the ...
When the tolerance factor of a crystal is close to 1.0, the crystal structure is more stable and given a matrix composed of highly polarisable ionic species, ferroelectric properties are encouraged. Electronegativity difference, en, can also indicate the stability of the crystal structure, ...
X-ray diffraction data showed that 2–8mol% BiFeO 3 can dissolve into the lattice of BaTiO 3 and form single perovskite phase. The crystal structure changes from tetragonal to cubic phase at room temperature when 8mol% of BiFeO 3 was added into BaTiO 3 . Scanning electron microscope images...
All ceramics show single pseudo-cubic perovskite crystal structure. Although the structure was not changed but other properties were much changed by heat-treatment. The normally cooled ceramic showed pinched' ferroelectric hysteresis loops with remanent polarization value of about 10C/cm(2). On the ...
Abstract In this paper, single-phase multiferroic ceramics of (1 − x) BaTiO3 − x BiFeO3 (BT − x BFO) were synthesized by solid-solution method in the wide range of material composition (x = 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray ...
CrystalstructureMagnetic spin structures in epitaxial BiFeO3 single layer and an epitaxial BaTiO3/BiFeO3 multilayer thin film have been studied by means of nuclear resonant scattering of synchrotron radiation. We demonstrate a spin reorientation in the 15 × [BaTiO3/BiFeO3] multilayer compared to ...
