We have synthesized Ba_{1-x}La_{x}Fe_{12}O_{19} (0 ≤ x ≤ 0.4) and BaFe_{12-y}Nd_{y}O_{19} (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 BaFe_{12}O_{19} were investigated. The highest coercive field was obtained for the sample having La content, x = 0.3.
