Box 54, TR-41470, Gebze, Kocaeli, Turkey We have synthesized Ba1−xLaxFe12O19 (0 ≤ x ≤ 0.4) and BaFe12−yNdyO19 (0 ≤ y ≤ 4) samples in ammonium nitrate melt and nitric acid. The effects of La and Nd doping on the microstructure and magnetic properties of BaFe12O19 were investigated. The highest coercive field was obtained for the sample having La content, x = 0.3.
