Magnetoelectric effects are discussed in multiferroics with the perovskite structure: bismuth ferrite, rare-earth orthochromites, and Ruddlesden--Popper structures belonging to trigonal, orthorhombic, tetragonal syngonies. The influence of structural distortions on magnetic ferroelectric properties is studied, possible magnetoelectric (linear, quadratic, inhomogeneous) these materials determine...

Since 2007, at the Electron Science Research Institute (ESRI) nano-fabrication laboratories, Edith Cowan University, Australia, we have devoted research efforts to synthesis and characterization of bismuth-containing ferrite-garnet-type thin-film magneto-optic (MO) materials different compositions. We report on growth characteristics radio frequency (RF) magnetron sputtered bismuth-substituted ...

BiFeO heterostructures were manufactured using intermittent sputtering technology on the surface of a single crystal substrate MgO(001) 3 /(Sr, Ba)Nb 2 O 6 . Studies structure, thickness profile composition, morphology and dielectric characteristics materials have been carried out. It is established that despite formation two types orientation domains (±18.4 o ) in layer (Sr, , upper ratio tota...

Iron oxide and bismuth powder are synthesized by the liquid phase precipitation method. Then a certain proportion of iron oxide, sodium chloride mixed ground to prepare ferrite precursor molten salt The precursors calcined at different temperatures obtain photocatalyst. By studying degradation performance photocatalysts for methyl orange dyes, best conditions dyes found. experimental results sh...

Abstract The BiFeO 3 (BFO) thin films made by the electron beam evaporator are systematically investigated. As most difficult part of this work, preparation process is repeated until optimal deposition power and elemental composition BFO obtained. With help X-ray diffraction Raman spectroscopy, we specify precisely that sample annealed at temperature 650 °C purest phase with rhombohedral R3c st...
