چکیده انگلیسی
Bi1âxPrxFe0.97Mn0.03O3 (x=0.00, 0.05, 0.10, 0.15, 0.20) thin films were deposited on FTO/glass substrate using chemical solution deposition. The influences of Pr doping on the crystalline structure and multiferroic properties were investigated. In the X-ray diffraction and Raman spectra results, the crystal structures of Bi1âxPrxFe0.97Mn0.03O3 films revealed a gradual transformation from the trigonal structure to the tetragonal structure. The leakage current densities of Bi1âxPrxFe0.97Mn0.03O3 films are one order of magnitude lower than that of BiFeO3. Compared with unsaturated polarization-electric field hysteresis loop of BiFeO3 film, the Pr and Mn co-doped BFO films have significantly improved ferroelectric properties. The improved remnant polarization (Pr=91.3 µC/cm2) and the positive switching current (I=0.028 A) have been observed in Bi0.85Pr0.15Fe0.97Mn0.03O3 film. The improved electrical properties are attributed to the structure transformation, increasing grain boundaries, low oxygen vacancies ratio and increasing Fe3+ concentration. In addition, the saturation magnetization of Bi0.85Pr0.15Fe0.97Mn0.03O3 film is 1.81 emu/cm3, which is approximately three times higher than pure BiFeO3 (Ms=0.67 emu/cm3).
