Effect of Mn doping on the structural, spectral, electrical, ferromagnetic and piezoelectric properties of 0.7BFO-0.3BTO lead-free ceramics

Piezoelectric properties of mechanochemically processed 0.67BiFeO3-0.33BaTiO3 ceramics

“…An overview of ferro-, piezo-and dielectric properties of materials from the literature with similar composition as ours is presented in Table S.2 (supplementary information). All the P r values are in the high end compared to the previously reported values (P r =15-30 µC/cm 2 ) for the same composition [38,[42][43][44][45]. Since higher polarization values are typically observed for more homogeneous BF-BT ceramics (e.g.…”

“…Here we can see that the S-samples all have significantly lower d 33 values (33-47 pC/N) than the U-samples (97-115 pC/N). The highest S.2) [38,[42][43][44][45].…”

Elucidating the capacitive behavior of Gd-doped BNT-BKT-BT electrodes in All-in-One supercapacitor devices

“…However, they significantly contribute to the material's conductivity, mostly by creating defect centers such as oxygen vacancies, which can serve as charge carriers and enhance the electrical conductivity of the ceramics. On the other hand, metal ion doping can sometimes introduce structural changes in ceramics, leading to new or modifying existing phases [8]. Thus, the capacitive behavior of the ceramics can be affected by changing their dielectric constant or altering the energy landscape of the defect centers.…”

Modifying electric and multiferroic properties of lead-free 0.7BFO-0.3BTO ceramics via Sm and Ga co-doping

“…However, an effective approach to overcome these limitations along with improvement of electrical, multiferroic, as well as piezoelectric properties of BFO is to create solid solutions by combining it with another ABO 3 type perovskites. This involves combining BFO with compounds such as BaTiO 3 , CaTiO 3 , NaNbO 3 , SrTiO 3 and many others [21][22][23][24]. On account of its exceptional properties, including high Curie temperature (T C ) exceeding 580 °C, remarkable ferroelectricity, and excellent piezoelectricity, the BiFeO 3 -BaTiO 3 (BFO-BTO) system has garnered significant attention [21].…”

BaTiO 3 (BTO) stands out as the pioneering ferroelectric polycrystalline ceramic material ever discovered.…”
