Abstract
Cd/Ni-substituted strontium hexaferrite SrFe12−2xCdxNixO19 (for x = 0.0, 0.1, and 0.2) has been prepared via sol–gel method. The synthesized samples have been sintered at 950 °C. Powder X-ray diffraction (XRD) results establishes the single-phase magnetoplumbite structure. Lattice parameters (a and c), cell volume (Vcell), and crystallite size (D) have been determined. The magnetic characteristics such as saturation magnetization (Ms), retentive magnetization (Mr), and coercive field (Hc) have also been determined from VSM data (hysteresis loop). The value of Ms increases, and Mr and Hc decreases with increase in dopant concentration. FT-IR and Raman analysis establishes the metal–oxygen vibrations present in various sites. UV–Vis–NIR spectra reveals that the synthesized samples are transparent in the entire visible region and hence they can be used in optoelectronic applications. The study reveals that Cd/Ni-substituted strontium hexaferrites are suitable candidates for optoelectronic devices, microwave devices, and recording media.
