Abstract:

PrBi4Fe0.5Co0.5Ti3O15 compounds were prepared either by conventional solid-state reaction method or by two-step method. X-ray diffraction analyses indicate that the PrBi4Fe0.5Co0.5Ti3O15 samples which were synthesized by the conventional solid-state reaction method favors the formation of single phase four-layer Aurivillius phase more easily than the samples prepared by the two-step method. The multiferroic properties of the samples at room temperature were demonstrated by ferroelectric and magnetic measurements. The samples exhibit significantly enhanced magnetic properties by Pr/Co co-substitution. The remnant magnetization (2Mr) of the samples prepared by the conventional solid-state reaction and two-step methods are 0.315 and 0.576 Am2/kg, respectively, approximately five orders larger than that of the reported Bi5FeTi3O15 ceramics (2.7×10-6 Am2/kg) and two orders of the reported Co-doped Bi5FeTi3O15 ceramics (7.8×10-3 Am2/kg).

Key words: multiferroic ceramics, solid state reaction, magnetic property, dielectric property
