Abstract

We investigated the average crystal structure and microstructures of LuFe_0.56Ti_0.44O₃ by transmission electron microscopy (TEM) in combination with dielectric measurements. In this work, high-quality polycrystalline samples of LuFeM_0.56Ti _0.44O₃ were successfully synthesized in air by the conventional solid-state reaction. The average crystal structure at room temperature is characterized by a hexagonal structure (space group: P6 ₃cm). Dielectric measurements revealed that LuFe _0.56Ti_0.44O₃ shows broad dielectric peaks at approximately 450 and 580K, one of which is considered to originate from the formation of polar domains at the nanometer scale.
