ABSTRACT: The Y-type hexaferrites Sr2CO2-XBixFe12O22 (x=0.0, 0.05 and 0.10) has been synthesized using Sol Gel technique. The structural and magnetic outcome of Bismuth dopant was investigated by XRD, FTIR and VSM study. The XRD reveal the formation of Y-type hexaferrite. Two prominent peaks were observed near 400-600 cm-1 in FTIR spectra indicates twisting and broadening of Fe-O bond at octahedral and tetrahedral sites, respectively. The squareness ratio (Mr/ Ms) of less than 0.5 for all compositions reveals that nanoparticles are haphazardly oriented multi domain particles.
