| Popis: | Multiferroic materials have attracted extensive attention due to their potential applications in multiple state memory elements and other integrated ferroelectric devices. In the present work, we synthesized Bismuth ferrite (BiFeO3-BFO) multiferroic nanoparticles using Sol–gel(SGBFO)and Microwave Assisted Combustion method(MWBFO). We investigated the impact of synthesis routes in the magnetic poperties of BFO. The X-ray diffraction analysis reveals a pure phase Rhombohedral for sol–gel and Hexagonal structurefor microwave assisted combustion methods along with some secondary phases of Bi2Fe4O9. The crystallite size is found to be 32.6 nm and 36.2nm for SGBFO and MWBFO. The FTIR spectrum shows strong absorption around 400–600 cm−1for the materials prepared by both the methods. This reveals the formation of perovskite structure of BFO prepared by both the methods. Non uniform shaped agglomerated nano particles, sheets and rods are seen in Field Emission Scanning Electron Microscopy (FESEM) images. VSM analysis shows synthesis method is a highly effective parameter in determining the properties of nano particles. Weobserved decrease in coercicvity of the BFO synthesized by MWBFO method. |
