Bulk ceramic compositions of BiFeO3 (BFO), (Bi0.90Pr0.10)FeO3 and (Bi0.90Pr0.10)Fe0.95T0.05O3 [T=Cu, Co] were synthesized using conventional solid-state reaction route. Confirmation of phase formation was established by x-ray diffraction technique. The relative shifts in the most intense peaks of the pristine BFO sample indicated the substitution of rare-earth and transition metal ions at their respective sites. The grain size decreased with the A- and B-site substitution in BFO. In Raman spectra, Pr and Co/Cu co-substituted BFO samples exhibit hardening of the low-frequency modes. It is also observed that the line-widths of Raman peaks are broadened as compared with those of the pure sample. The saturation magnetization enhanced with Pr and Co co-substitution in BFO with a value of 1.5 emu/g.
