We report the fabrication of novel multiferroic nanostructured bismuth ferrite (BiFeO(3)) fibers using the sol-gel based electrospinning technique. Phase pure BiFeO(3) fibers were prepared by thermally annealing the electrospun BiFeO(3)/polyvinylpyrrolidone composite fibers in air for 1 h at 600 °C. The x-ray diffraction pattern of the fibers (BiFeO(3)) obtained showed that their crystalline st...
Solid-state sintering method was used to prepare ceramic materials based on bismuth ferrite, i.e., (BiFeO3)1 - x -(BaTiO3) x and Bi1 - x Nd x FeO3 solid solutions and the Aurivillius Bi5Ti3FeO15 compound. The structure of the materials was examined using X-ray diffraction, and the Rietveld method was applied to phase analysis and structure refinement. Magnetoelectric coupling was registered in ...
A series of bismuth based superconducting materials doped with galliumBi Pb Sr Ca Cu Ga O 1.7 0.4 2 2 3-x x y (x = 0.0, 0.02, 0.04, 0.06, 0.08 and 0.10) was synthesized by Simple solid-state reaction method. The samples were characterized by X-ray diffraction, EDX analysis and electrical resistivity and ac magnetic susceptibility measurements. All the samples consist of both low-T (2212) and Hi...
