In this study, we synthesized a series of Erbium-substituted X-type hexaferrites, Ba2Co2ErxFe28-xO46 (x = 0.00, 0.04, 0.08, 0.12, 0.16, and 0.20), employing a heat treatment method at 1350 °C for 6 hours. X-ray diffraction (XRD) analysis revealed the presence of X, W-type, and α-Fe2O3 phases in the x = 0.00 sample, while Er-substituted samples exhibited the presence of X and W phases. The room temperature Mössbauer spectra were fitted with five sextets, providing insights into the local magnetic environments. The observed variation in saturation magnetization (MS) finds support in Mössbauer spectroscopy, with the highest values of MS (52.29 Am2/kg) and anisotropy field (Ha) (1370 kA/m) identified in the x = 0.12 composition. Additionally, a maximum relative area (~69%) for spin-up sites (k+a+b) was also observed for x = 0.12 composition.
