Summary: The combustion-based synthesis of BiFeO3 (BFO) and Gd:BFO perovskite nanoparticles was presented. XRD analysis showed that the undoped BFO sample had a single perovskite phase with a rhombohedral structure, while the Gd-doped samples exhibited a structural phase transformation from rhombohedral to orthorhombic. The presence of Bi3+, Gd3+, Fe2+, and O2+ ions in the perovskite samples was confirmed by XPS, and elemental functional groups were detected by FT-IR spectroscopy. The direct band gap decreased as the Gd concentration increased. The synthesized catalysts, particularly Gd:BFO (x = 0.25), exhibited higher conversion and selectivity efficiencies for glycerol in catalytic oxidation studies.

Summary: TiO2-doped nanocrystalline Ni0.4Cu0.3Zn0.3Fe2O4 ferrites were synthesized using the sol-gel method, exhibiting cubic spinel structure and semiconducting properties with increasing TiO2 doping level. The addition of TiO2 led to a decrease in lattice parameter, band gap energy, and saturation magnetization of the ferrites, confirming the soft magnetic behavior at room temperature. The presence of a nonmagnetic TiO2 secondary phase was confirmed by Mossbauer study, contributing to the decrease in magnetic behavior of the doped ferrites.

Summary: This study investigates the physical properties of La3+-doped Cu-Cd ferrites (CCF ferrites). The CCF ferrites, synthesized using the sol-gel method, exhibit a cubic spinel structure confirmed by Rietveld refinement. The morphology analysis reveals the presence of cubical and triangular crystallites. Increasing La3+ content enhances magnetic permeability and reduces magnetic loss. Moreover, increasing temperature leads to improved permeability. The increase in permittivity and decrease in ac conductivity can be attributed to an increase in grain size and a reduction in grain boundaries as explained by the Maxwell-Wagner model. The magnetic and electrical performance of CCF ferrites demonstrate their potential use in microwave devices and high-frequency applications.

Summary: The Ag+ doped nanocrystalline nickel ferrites, NiAgxFe2-xO4 (NAF) with x = 0-0.1 were synthesized using aloe vera extract as a solvent. XRD analysis confirmed the creation of spinel phase within the pristine Ni ferrite, with the presence of nano Ag particles in doped NAF. TEM analysis confirmed the nanocrystalline nature of the ferrites, while SEM analysis revealed the layered arrangement of spherical nanoparticles within the NAF crystals. The optical properties of NAF crystals showed a decrease in band gap energies with increasing Ag+ composition due to the contribution of delocalized electrons in direct optical transitions.
