Abstract
Zr- and Pb-doped strontium hexaferrite is synthesized by sol-gel auto combustion technique. Recorded powder X-ray diffraction (PXRD) patterns reveal the single phase hexaferrite formation. The synthesized samples are transparent up to 800 nm. Infrared spectral analysis establishes the tetrahedral and octahedral site metal-oxygen vibrations. Magnetic analysis reveals reduction in saturation magnetization (Ms), remnant magnetization (Mr) and increase in coercivity (Hc) due to the increase in dopant concentration. The study reveals that as the dopant concentration increases, the samples become more and more hard magnetic.
