The crystal structure, magnetic and local ferroelectric properties of polycrystalline Bi 1Γx Gd x FeO 3 (x = 0.1, 0.2, 0.3) samples were investigated at room temperature. Gadolinium substitution was found to induce a polar-to-polar R3c ? Pn2 1 a structural phase transition at x % 0.1. Increasing the
Spinel-perovskite nanocomposites of xCrFe 2 O 4 -(1 Γ x)BiFeO 3 with xΒΌ 0.0, 0.1, 0.2, 0.3, 0.4 were prepared by sol gel method. The XRD showed the phase formation of nanocomposites at 700 1C. Particle size was observed to be $ 100 nm by TEM. The variation of dielectric constant and dielectric loss
The influence of an external electric field E is studied on the phonon properties of multiferroic BiFeO 3 and hexagonal RMnO 3 materials using a microscopic model and Green's function technique. The phonon energy decreases whereas the damping increases with enhancing of E.
Dielectric, magnetic and ferroelectric properties of Bi 1-x Ba x FeO 3 (x= 0.1, 0.2 and 0.3) synthesized by solid state reaction method are reported. X-ray diffraction pattern showed that Bi 1-x Ba x FeO 3 was single phase. Ba substitution has led to a decrease in grain size and hence an increase in
