We have investigated an average crystal structure and microstructures in LuFe$$_{0.56}$$Ti$$_{0.44}$$O$$_{3}$$ by the transmission electron microscopy (TEM), in combination with the dielectric measurements. In this work, high-qualitypolycrystalline samples of LuFe$$_{0.56}$$Ti$$_{0.44}$$O$$_{3}$$ were successfully synthesized in air by the conventional solid state reaction. The average crystal structure at room temperature is characterized by the hexagonal structure (space group: $$P$$6$$_{3}$$ cm). Dielectric measurements revealed that LuFe$$_{0.56}$$Ti$$_{0.44}$$O$$_{3}$$ shows broad dielectric dispersion around 570 K, which should originate from the formation of the polar domain structures on the nanometer scale.

We have investigated the crystal structure and physical properties of RFe$$_{0.56}$$Ti$$_{0.44}$$O$$_{3}$$(R=Lu,Yb). The samples were prepared by the solid-state reaction method in air. X-ray and electron diffraction measurements showed that the materials have the same crystal structure as that of multiferroic RMnO$$_{3}$$. Magnetic measurements showed the absence of magnetic transition below 400 K. Dielectric measurements showed the peak of dielectric constant above room temperature, suggesting a existence of ferroelectric phase transition at high temperatures.
