Effects of rare earth manganites on structural, ferroelectric, and magnetic properties of BiFeO3 thin films

“…While our pure BFO did not show ferroelectric switching, 11 well-shaped and saturated P-E hysteresis loops were obtained for doped films obtained at room temperature and 10 kHz frequency, Fig. 4.…”

“…[5][6][7][8][9][10] However, systematic analysis of how doping elements affect structure and through it properties is still lacking. In previous work 11 we have shown that the addition of LaMnO 3 ͑LMO͒ to BFO at concentrations of up to 10 mol % could lead to improved electrical and polarization properties. In a systematic study using x-ray diffraction ͑XRD͒ and Raman spectroscopy it appeared that the addition of LMO was responsible for substantial structural changes, including a monoclinic to orthorhombic structural transition and the appearance of Jahn-Teller distortion.…”

Multiferroism in orientational engineered (La, Mn) co-substituted BiFeO3 thin films

“…[14][15][16][17][18][19][20][21] Nevertheless, ferroelectric and magnetic behaviors of the substituted BFO thin films have great discrepancy across many research reports. The (La, Mn) co-substituting has been proposed as a promising strategy to simultaneously optimize ferroelectric and ferromagnetic properties, [22][23][24] but the cosubstitution effects of La and Mn on BFO so far have only been examined in form of polycrystalline thin films with rather scattered physical properties. In order to provide the information for revealing the intrinsic mechanism underlying the co-substitution without influences of extrinsic defects, it is desirable to investigate co-substitution effect along specific crystallographic orientation in epitaxial thin films.…”

Synthesis of multifunctional multiferroic materials from metalorganics

“…Additionally, current densities for the doped films measured at 10 K were observed to be much lower than the densities at room temperature indicating the presence of undesirable conduction paths even after doping with rare-earth ions. Habouti et al [85] fabricated 0%, 5% and 10% LaMnO 3 -doped BiFeO 3 polycrystalline films on platinized substrates. The leakage current densities for 5% LaMnO 3 -doped BiFeO 3 films was lower then pure BFO, however at higher doping content, the properties deteriorated.…”
