This study was intended to assess the role of carboxymethyl cellulose (CMC) as a chelating agent in the synthesis of barium hexaferrite (BaFe12O19:BaF). The effect of varying concentrations of CMC was studied via the sol-gel auto-combustion method following the requirements of green chemistry synthesis. The formation of BaF nanoparticles was confirmed using XRD, SEM, EDS, VSM, FTIR and UV-Vis-DRS techniques. The characterized XRD peak indicates the formation of good quality crystalline samples at 6% (w/v) of CMC concentration. SEM analysis suggested that the synthesized BaF is spherical, with sizes ranging from 10-15 nm. The M-H hysteresis loops obtained for the samples showed their soft and hard magnetic behaviour. With the increasing CMC concentration, magnetism becoming harder and an in
