Notes:
BaFe12O19 and La-Mn substituted M-type Ba hexaferrites were synthesized by sol-gelmethod and characterized by XRD, SEM and FTIR. The results showed that citric acid played animportant role in the forming process of BaFe12O19. BaFe12O19, synthesized under lower citric acidand presintered at 450°C, showed improved hexagonal crystal phase. BaLa0.5Fe11.5O19 andBa(MnLa)0.5Fe11O19 showed similar crystal structure to BaFe12O19 while Ba0.5Mn0.5Fe12O19 andBa0.5Mn0.5La0.5Fe11.5O19 showed changed crystal constant. FTIR analysis proved the formation ofnew mental-oxygen bond in substituted hexaferrites
