Helium implantation in epitaxial thin films is a way to control the out-of-plane deformation independently from in-plane strain controlled by epitaxy. In particular, means of helium microscope allows for local and patterning down nanometer resolution, which interest device applications. We present here study bismuth ferrite (BiFeO3) where was patterned locally implantation. Our combined Raman, ...

• BiFeO 3 particles were embedded in non-conducting non-piezoactive PVDF terpolymer. Dielectric and piezoelectric properties of -PVDF composite with different volume fraction studied. The charge voltage coefficients granular determined by using Yamada Poon model. is an interesting multiferroic material potential use sensors transducers. However, the high coercive field low dielectric strength t...

Bismuth ferrite (BiFeO3) possesses a non-collinear spin order while the ferroelectric breaks space inversion symmetry. This allows efficient electric-field control of magnetism and makes it promising candidate for applications in low-power spintronic devices. Epitaxial strain effects have been intensively studied exhibit significant modulation magnetic bismuthBiFeO3, but tuning its structure wi...

Bismuth ferrite, BiFeO3, is a multiferroic solid that attracting increasing attention as potential photocatalytic material, because the ferroelectric polarization enhances separation of photogenerated carriers. With motivation finding routes to engineer band gap and alignment, while conserving or enhancing properties, thermodynamic, electronic, properties BiCoxFe1?xO3 solutions (x = 0, 0.0625, ...

Magnetic, dielectric and calorimetric studies on 0.9BiFeO3-0.1BaTiO3 indicate strong magnetoelectric coupling. XRD studies reveal a very remarkable change in the rhombohedral distortion angle and a significant shift in the atomic positions at the magnetic Tc due to an isostructural phase transition. The calculated polarization using Rietveld refined atomic positions scales linearly with magneti...

Electrostatic-force-sensitive scanning probe microscopy (SPM) is used to investigate grain boundary behavior in polycrystalline BiFeO3 ceramics. Scanning surface potential microscopy (SSPM) of a laterally biased sample exhibits potential drops due to resistive barriers at the grain boundaries. In this technique, the tips acts as a moving voltage probe detecting local variations of potential ass...

Using high temperature solid state reaction technique ceramic composites (1-x)BiFeO3 - xBa5TbTi3V7O30 having different x values are prepared. Basic crystal qualities studied using XRD which shows that there’s a formation of BiFeO3 and Ba5TbTi3V7O30 phases. There observed change in the basic structure as changes is most distorted for = 0.5. From SEM study, it found grain size minimum pure ferroe...
