摘要

Cd/Ni-substituted strontium hexaferrite SrFe_(12-2x)Cd_xNi_x.O_(19) (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 (V_(cell)), and crystallite size (D) have been determined. The magnetic characteristics such as saturation magnetization (M_s), retentive magnetization (M_r), and coercive field (H_c) have also been determined from VSM data (hysteresis loop). The value of M_s increases, and M_r and H_t 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.
