Perovskite single-phase ceramics of Mn-doped (1 − x)BiFeO3xBaTiO3 with a wide range of composition (x = 0–1.0) were prepared using the solid-state reaction. Remanent polarization Pr, was observed for (1 − x)BiFeO3xBaTiO3 (x = 0.15–1.0) and remanent magnetization Mr, was observed for (1 − x)BiFeO3xBaTiO3 (x = 0.15–0.8). The maximum value of Pr = 39 µC/cm2 was obtained at x = 0.33 with a high Curie temperature TC, of 420°C. The maximum value of Mr = 0.18 emu/g was obtained at x = 0.33 with a high magnetic Curie temperature TCM, of 360°C. A multiferroic phase diagram is constructed from the TC and TCM observed for the samples. A multiferroic state is maintained to a high temperature up to 250°C in the wide range of x = 0.15–0.55.
