摘要: Abstract Mn-doped BiFeO 3 (BiFe 1–x Mn x O , = 0, 0.03, 0.05, 0.10, 0.15 and 0.20) polycrystalline multiferroic thin films were successfully synthesized using the facile sol-gel spin-coating method. The crystal structures, surface features, elements valences, magnetic properties of as-prepared samples systematically explored. X-ray diffraction Raman spectroscopy studies revealed substitutions into Fe site a rhombohedral-to-orthorhombic phase transition. Field Emission Scanning Electron Microscopy showed decrease in average particle sizes an improvement morphology with increasing concentration substitutes. Energy-dispersive confirmed doping 2+ samples. photoelectron indicated co-existence /Mn 3+ ions doped films. remnant magnetization value BiFe 0.90 0.10 film was found to be approximately six times than that pure under field 10 kOe. enhanced property mainly ascribed structural distortion spin cycloid enhancement super-exchange interaction between (Mn ) 2- ions.
