Influence of Ruthenium on flexible polyvinylidene fluoride/BiKFe2O5 multiferroic nanocomposite

In the present work, we report synthesis, structural, magnetic and dielectric studies of Ruthenium (Ru) doped BKFO (BiKFe2O5) multiferroic nanocomposite. The Multiferroic nanopowders were synthesized using coprecipitation method and annealed powders were dispersed in Polyvinylidene fluoride (PVDF) matrix. The heat treated nanopowders were characterized using X-ray Diffraction, Transmission Electron Microscopy, Vibration Sample Magnetometer, and Dielectric measurements were carried out on films. All the reflections from XRD spectrum are indexed with orthorhombic structure (space group Pbnm). Particle size measured from TEM is observed as less than 100 nm. The EDS spectrum confirms the presence of all the elements in respective concentrations in the synthesized samples. Enhancement in Ferromagnetic nature and influence on dielectric behaviour was observed with Ru doping. (X) 2019 Elsevier Ltd. All rights reserved.
