Title: Magnetic properties of Bi(Fe{sub 1-x}Cr{sub x})O{sub 3} synthesized by a combustion method

Abstract

Single-phase samples of Bi(Fe{sub 1-x}Cr{sub x})O{sub 3} with x=0, 0.1, and 0.2 were synthesized by a combustion method. X-ray diffraction reveals that the lattice parameters of Bi(Fe{sub 1-x}Cr{sub x})O{sub 3} perovskites decrease linearly with the Cr content, indicating that Cr ions substitute for Fe ions to form a solid solution. X-ray photoelectron spectroscopy investigation shows that Cr ions have the Cr{sup 3+} valence state in Bi(Fe{sub 1-x}Cr{sub x})O{sub 3}. The frequency dependence of dielectric constants was investigated at room temperature. Magnetic measurements show hysteresis loops at both 5 and 300 K and the substitution of Cr for Fe enhances the magnetization.
