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.
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
