This study focuses on the synthesis, structural, electrical, and magnetic characterization of Sr1-XLaXFe12O19 (SLFO) nanoparticles using the hydrothermal technique. The lattice constants of SLFO were found to increase with X. The optical bandgap also increased with dopant content. The electrical properties and magnetization of SLFO were investigated as well.
The current work is mainly devoted to the synthesis, structural, electrical, and magnetic characterization of Sr1-XLaXFe12O19 (X = 0.2-0.8) (SLFO) nanoparticles synthesized via the hydrothermal technique. The hexagonal peaks were determined using X-ray diffraction analysis. The obtained results indicated that the lattice constants were noted to be increasing from 0.58801 to 0.58825 nm (a = b), and 2.30309 to 2.30341 nm (c) with increase of in 'X'. The morphological studies ensured that the grains as well as nanoparticles of SLFO acquired almost spherical shape. The optical properties were investigated using FTIR and UV-Visible spectra. The optical bandgap (E-g) of SLFO was found to be increasing from 1.866 to 2.118 eV with increase of dopant content. The electrical properties of SLFO were studied in detail as a function of temperature, and frequency. In addition, the dielectric modulus, and impedance spectroscopy analysis was carried out to describe the space charge polarization, and electric conduction mechanism, respectively. The hysteresis loop (M-H curves) of SLFO revealed the decrease of magnetization from 36.34 to 7.17 emu/g with increase in 'X'.
