In this work we have prepared a series of BaFe 12 O 19 :xEu 3+ (x=0 to 2 mol %) samples by combustion method. The prepared samples were characterized by PXRD, TEM and FTIR. The structural analysis of PXRD pattern affirms that the specimens have space group p6 3 /mmc and hexagonal structure. The TEM micrographs show hexagonal plate like structure and the FTIR spectra show vibration between the 4f 1 and 4f 2 crystallographic sites of the ferric ions. The absorption spectra of the prepared specimen were obtained from UV-vis spectroscopy. The calculated band gap values range from 3.99 eV to 2.29eV.
