“…The electrical properties can be modified by doping on A or B-site of BFO. Rhagavan et al prepared (Nd, Cu) co-doped BiFeO3 thin films by chemical solution deposition method and observed enhanced electrical and ferroelectric properties in co-doped thinfilms [7]. Zhang et al reported an increase in ferroelectric properties of (Nd, Co) co-doped BiFeO3 thinfilm when compared to single doped sample [8].…”

“…In order to overcome the above problems and improve the multiferroic properties, a chemical modification using rare earth (or alkaline earth) and transition metal ions into Aand B-sites of the perovskite BFO is strongly recommended, basing on the fact that A-site and B-site codoping could make favorable environment for the enhancements of polarization and magnetization through lattice distortion and suppression of cycloid spin structure [7,8]. Assuredly, double element codoping can effectively reduce the impurity phases, the formation of defects and the chemical fluctuation, such as Tb/Mn [9], Ca/Mn [10], Nd (or Sm)/Cr [11], La (or Pr)/Co [12] and et al However, few studies about using rare earth, alkaline earth and transition metal ions co-doped BFO have been reported. Therefore, it is considerable to probe further into the feasibility of enhanced ferroelectric and ferromagnetic properties of the rare earth, alkaline earth and transition metal ions co-doped BFO thin films.…”

Pure BiFeO 3 (BFO) and Bi 0.85-x Pr 0.15 Sr x Fe 0.97 Mn 0.03 O 3 (BPS x FMO, x = 0.02-0.05) thin films were deposited on fluorine-doped SnO 2 (FTO/glass) substrates by a sol-gel method. The systematic studies of crystalline structure, surface morphologies, leakage conduction mechanisms, ferroelectric and magnetic properties of pure BiFeO 3 and Bi 0.85-x Pr 0.15 Sr x Fe 0.97 Mn 0.03 O 3 thin films were investigated. X-ray diffraction patterns, Rietveld analysis and Raman scattering spectra reveal that the (Pr, Sr and Mn) co-doped BiFeO 3 thin films give rise to a trigonal (R3m: R) structure transition with respect to the original rhombohedral structure of pure BiFeO 3 film. Fowler-Nordheim tunneling conduction mechanism dominates the leakage current of all the films in the relatively high electric field. The significantly enhanced ferroelectric properties of the Bi 0.85-x Pr 0.15 Sr x Fe 0.97 Mn 0.03 O 3 thin films were observed in comparison with pure BiFeO 3 film. In addition, the BPS 2 FMO film shows the enhanced ferromagnetism with the saturation magnetization (M s * 1.97 emu cm -3 ), which is almost three times larger than that of pure BFO film (M s * 0.67 emu cm -3 ), as a result of the small grain size effect and the collapse of space modulated spin structure by the structure transition.

“…The oxygen vacancy could form a defect dipole with 2Bi 0 Sr as [2Bi 0 [20]. Thus, the dipoles formed by the charge compensation could lead to the increase of the leakage current and increase of the polarization in the B 1-x Sr x FMC thin films [22].…”

“…According to the group theory, 13 Raman active modes (4A 1 ? 9E) are predicted for the rhombohedrally distorted R3c space group [20]. Based on previous data, three peaks at 144, 172, 223 cm -1 are assigned as A 1 modes, while the subsequent peaks at 268, 374, 480, 521 and 629 cm -1 are denoted as E modes.…”

Sr 2? -doped B 1-x Sr x Fe 0.94 (Mn 0.04 Cr 0.02 )O 3 (B 1-x Sr x FMC, x = 0.00, 0.05 and 0.09) thin films were prepared on FTO/glass (SnO 2 : F) substrates by using a sol-gel spin-coating method. X-ray diffraction (XRD), Rietveld refined XRD data and Raman scattering spectra illustrate a structural evolution from trigonal (R3c: H) to tetragonal (P4) occurs in B 1-x Sr x FMC thin films with the increase of Sr 2? concent. Superiorly multiferroic and dielectric properties were obtained in the B 1-x Sr x FMC thin films, e.g., large remanent polarization value, a high dielectric constant (P r = 139.21 lC/cm 2 and e r = 396.7 for x = 0.09) and large saturation magnetization (M s = 2.08 emu/cm 3 for x = 0.05). The leakage current density of B 1-x Sr x FMC thin films is increased with increasing Sr 2? concentration, wherein the leakage current density of all the B 1-x Sr x FMC films is of the order of magnitude of 10 -5 A/cm 2 , which are still lower than that in the pure BFO film (10 -3 A/ cm 2 ).
