There have been a large number of papers on bismuth ferrite (BiFeO3) over thepast few years, trying to exploit its room-temperature magnetoelectricmultiferroic properties. Although these are attractive, BiFeO3 is not the idealmultiferroic, due to weak magnetization and the difficulty in limiting leakagecurrents. Thus there is an ongoing search for alternatives, including suchmaterials as gallium ferrite (GaFeO3). In the present work we report acomprehensive study of the perovskite PbTi1-xPdxO3 with 0 < x < 0.3. Our studyincludes dielectric, impedance and magnetization measurements, conductivityanalysis and study of crystallographic phases present in the samples withspecial attention paid to minor phases, identified as PdO, PbPdO2, and Pd3Pb.The work is remarkable in two ways: Pd is difficult to substitute into ABO3perovskite oxides (where it might be useful for catalysis), and Pd is magneticunder only unusual conditions (under strain or internal electric fields). Thenew material, as a PZT derivative, is expected to have much strongerpiezoelectric properties than BiFeO3.
