Abstract

Slightly Mn and Mg co-doped BiFeO₃ films (BiFeO₃, BiFe_0.95Mg_0.01Mn_0.04O₃, BiFe_0.94Mg_0.02Mn_0.04O₃ and BiFe_0.93Mg_0.03Mn_0.04O₃, xBFMMO, x = 0, 0.01, 0.02 and 0.03) have been grown on Si (1 0 0) substrates by sol-gel technique. Rhombohedral lattice structure and phase transition is confirmed by X-ray diffraction and Raman spectroscopy. The improved surface morphology and decreased grain size of films can be observed in SEM micrographs due to the influence of Mn and Mg co-doping. Blue emissions of xBFMMO films can be found in Photoluminescence spectra, meanwhile the nonlinear shift of emission peaks imply the variation of bandgap. Room-temperature magnetization versus magnetic field (M-H) curves exhibit enhanced saturation magnetization compared with parental BiFeO₃, which can attribute to destroyed spin cycloid and released locked magnetization. These properties offer a great potential on the multiferroic information storage application.
