An experimental approach for synthesis of Fe-Al-O multiferroic fibrous material

Basic principles of the electro-hydrodynamics are applied for synthesis of solid state
Fe-Al-O multi-ferroic fibrous material. For that purpose stable blend spinning solutions
comprised of a high molecular assisting organic polymer and salts of iron and aluminum are
developed. These solutions are tested under electrospinning conditions and synthesis of
homogeneous as spun non-woven mats characterized by fibre mean diameters in the microand
nano-size range is successfully demonstrated. Multi-step thermal procedure is applied for
the consecutive solvent evaporation, polymer pyrolisis and final fibre calcination. Electronoptical
imaging technique and XRD are applied for revealing the sample morphology and the
phase composition correspondingly. The results obtained outline the wide possibilities for
fabrication of multi-ferroics fibrous nano-materials on the basis of Fe-Al-O.
