The undoped and Ca‐doped BiFeO3 nanoparticles of different particle size were synthesised using sol‐gel. Ca‐doping induced structural transformation from rhombohedral to orthorhombic phase along with reduced crystallite size due to its smaller ionic radii. Morphological analysis showed increase in particle size from 11 to 50 nm on increasing calcination temperature from 450 to 650 °C. Magnetic and electrical studies revealed enhancement in magnetism as well as dielectric constant and polarisation values with Ca‐doping. When the particle size of Ca‐doped BiFeO3 nanoparticles was further reduced, these values registered remarkable enhancement. Thermal analysis revealed charge compensation mechanism to occur via formation of oxygen vacancies on doping of Ca2+ ions in BiFeO3 lattice. The decreasing dielectric constant values indicating increasing oxygen vacancies content with particle size also point towards the similar charge compensation mechanism in the particle size varied Ca‐doped BiFeO3 nanoparticles.

“…It is observed that un-doped BFO exhibits ferromagnetic behavior in comparison to the antiferromagnetic nature of the bulk samples [21]. The ferromagnetic behavior of BFO may be due to the modulation of long-range spin cycloidal structure and also due to the antiferromagnetic nature of BFO [21].…”

Bi 1−x Ba x FeO 3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. The structural and magnetic properties were investigated using X-ray diffraction, SEM and VSM. As Ba 2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. The structural change might be an important factor for achieving the ferroelectric properties in this material. The lattice parameters were observed to increase with increase in Ba 2+ concentration. All the M-H loops showed the ferromagnetic behavior. Magnetization was observed to enhance with increase in Ba concentration. The enhancement in the magnetization due to Ba 2+ doping may be due to the replacement of Bi 3+ ions by Ba 2+ which might have resulted in the suppression of spiral spin structure.

“…In view of the reasons from literature survey, structural and optical properties of Badoped CdO films prepared by SILAR method [9], high T c ferroelectricity in Ba-doped ZnO nanoparticles [10], blue light emission from barium doped zinc sulfide nanoparticles [11] and, effect of particle size on multiferroism of barium-doped bismuth ferrite nanoparticles [12], it reveals that there is no report on the effect of Ba doping to the properties of CdO NPs. Therefore, we are reporting new results on the effects of Ba doping on the optical, structural and morphological properties of CdO NPs via TG-DTA, SEM, XRD, FT-IR, and UV-Vis-DRS techniques, respectively.…”
