Bi{sub 1-x}La{sub x}FeO{sub 3} (x = 0.0, 0.05, 0.10, 0.15) ceramic samples were prepared by solution combustion technique. X-ray diffraction patterns confirmed the formation of perovskite structured Bi{sub 1-x}La{sub x}FeO{sub 3} phase. Saturation magnetization (M{sub s}) increases with increasing La concentration from x = 0.0 to x = 0.15. Weak ferromagnetism is observed at room temperature in all the doped and undoped BFO samples. Mossbauer spectroscopy confirmed the presence of single-phase material for the doped compositions. Improvement in magnetic behavior appears to arise from a combination of the propensity of the samples to form pure phase material, partial destruction of spin cycloids and increased canting of spins.
