“…Magnetic moments at 10 K show true antiferromagnetic ordering in both prepared samples. However, possibly the enhancement in the resultant magnetic moment attributed to the broken cycloid spin structure caused by the variation in crystallographic arrangement with Pb and Ti doping in BiFeO 3 [35][36][37][38].…”

We report the synthesis and basic characterization details of bulk Bi1 − xPbxFe1 − xTixO3 (x = 0.05 and 0.1) polycrystalline samples, which have been synthesized using the conventional solid-state route. We studied the effects of partially doping of Pb and Ti ion on structural, vibrational, and magnetic properties of multiferroic BiFeO3. X-ray diffraction (XRD) was used for crystallographic studies, followed by Rietveld refinement, and phase formation of the compounds was confirmed, which indicates that the sample has rhombohedral (R3c, 100%) symmetry for x = 0.05 and R3c (98%) + P4mm (2%) symmetry for x = 0.1. X-ray absorption spectroscopy has been probed at Fe L2,3 and O K edges to determine the valence (charge) state of Fe in BiFeO3. Interestingly, the magnetic measurement results revealed the existence of spin reorientation transition in Pb and Ti-modified BiFeO3, which indicates that the BiFeO3 samples studied may find promising applications in memory and spintronic devices.

“…However, the volatilization of Bi ions and the variation of Fe 3+ into Fe 2+ ions result in the large leakage current of BF‐PT solid solutions. The ferroelectric and piezoelectric properties are much inferior to those of PZT ceramics 3‐6 . In addition, the overall ferromagnetic property is difficult to be observed in the bulk ceramics 7 …”

Dense 0.6(Bi0.9La0.1)(Ga0.05Fe0.95)O3‐0.4(Pb1‐xBax)TiO3 (BLGF‐PBT, x = 0, 0.1, 0.2, 0.3, and 0.4) ceramics with different Ba contents were prepared by the solid‐state reaction method, and effects of Ba contents on the structure and multiferroic properties were investigated. X‐ray diffraction results indicate that the Ba‐modified BLGF‐PBT ceramics exhibit single perovskite structure without detectable secondary phases, and a transition from tetragonal phase to rhombohedral one takes place with the increase of Ba content. The piezoelectric constant d33, remanent polarization Pr, and remanent magnetization Mr are improved by the Ba substitution simultaneously. Values of Pr, Mr, and d33 of BLGF‐PBT ceramics for the composition of x = 0.3 with the coexistence of tetragonal and rhombohedral phases are 20 μC/cm2, 0.05 emu/g, and 256 pC/N, respectively, much higher than those without Ba modification. The significantly improved d33 and Mr indicate that BLGF‐PBT ceramics with Ba modification provide alternative materials for multifunctional devices.

The 0.34BiFeO3‐0.46PbTiO3‐0.2BaZrO3 (BF‐PT‐0.2BZ) ternary solid solutions were prepared by the solid‐state reaction methods. Different amounts of Li2CO3‐Bi2O3 (LB) additives were introduced into the based materials after the calcination process. Upon using LB additives, the sintering temperature of BF‐PT‐0.2BZ ceramics was lowered to 950°C, while the relative density was enhanced to the highest of about 97% for LB of 1 wt%. XRD results indicate that BF‐PT‐0.2BZ ceramics exhibit the perovskite structure without detectable second phases. SEM images reveal that BF‐PT‐0.2BZ ceramics are well densified and the grain size is enhanced with the addition of LB. Moreover, the piezoelectric properties are enhanced significantly, achieving the highest d33 and bipolar strain of 350 pC/N and 0.53%, respectively, for BF‐PT‐0.2BZ ceramics with LB of 1 wt%. Our results indicate that low‐temperature sintered BF‐PT‐0.2BZ ceramics with excellent piezoelectric properties have promising applications in multilayer piezoelectric actuators.
