The effect of fabrication method on the structure of (100 − x ) wt% BaTiO 3 + x wt% La 0.7 Ba 0.3 MnO 3 ( BT + BLM ) and (100 − x ) wt% Na, Bi, Sr‐doped PZT + x wt% La 0.65 Pb 0.35 MnO 3 ( PZTNB ‐1 + PLM ) magnetoelectric ceramics was studied. Profound interdiffusion of two interacting phases occurs in nearly all cases. The BT + BLM and PZTNB ‐1 + PLM ceramics exhibit low piezoelectric parameters even with small manganite contents (10–20 wt%). The increased content of the magnetostrictive phase complicates the polarization process due to the high conductivity of La 0.7 Ba 0.3 MnO 3 and La 0.65 Pb 0.35 MnO 3 . Doping of BaTiO 3 and PZTNB ‐1 with small additions of manganite components affects piezoelectric properties, thereby lowering efficiency of the resulting material.
