Resumen:
The effects of varying the amount of lanthanum infusion on the barium ferrite characteristics were investigated in this study. An orthorhombic structure formed as a majority phase and traces of barium lanthanum iron oxide as segregated phases in the ferrites composites. The optical bandgap energy values of the BaLaxFe(2_x)O(4) nano-ferrites were 3.50-3.72 eV. SEM confirmed that the prepared nanoferrites had spherical morphology with size of 66.50-81.50 nm. The dielectric parameters of BaLaxFe(2_x)O(4) nanoferrites were studied in the specified spectrum, which revealed the La doped barium nanoferrites had a low dielectric constant and conductivity properties compared to the barium nanoferrites. The saturation magnetization (60.03-25.98 emu g(-1)) and coercivity (454.85-80.65 Oe) of the prepared nanoferrites were improved due to an effect of La3+ ions. Accordingly, the observed optical bandgap energy, dielectric constant, and magnetism could be employed in high-frequency magneto-optoelectronic systems.
