Abstract
0.67BiFeO3-0.33BaTiO3-xwt%Mn ceramics were synthesized using the SPS method. Fine BiFeO3-BaTiO3
ceramics with a morphotropic phase boundary were formed, as demonstrated by XRD and SEM. The
dielectric constants reached approximately 4000. The ferroelectric properties of Mn-doped BiFeO3-BaTiO3
were significantly improved compared with undoped BiFeO3-BaTiO3. The highest magnetic properties were
obtained when the sintering temperature was 820 ℃ and the doping content was 0.3 wt%, and were superior
to those fabricated using other methods. The Mn-doped BiFeO3-BaTiO3 multiferroic ceramic synthesized in
this work shows promise for application in data storage.
