Abstract

The effect of Mg-small doped on the structural and electrical properties of LaFe1-x MgxO3 ceramic materials was studied. A series of LaFe1-xMgxO3 (x= 0.01 and 0.05) perovskite material was synthesized via sol-gel method following by sintering process. Structural properties were investigated by using X-Ray diffraction (XRD). Rietveld refinement analysis have been done using Fullprof software. All of the samples are single-phase with orthorhombic crystal structure and Pnma space group. Lattice parameter slightly increases as the Mg-doping concentration increase. The impedance spectroscopy of the sample was characterized by using the RLC-Meter at a frequency range of 100 Hz - 1 MHz at room temperature. The electrical parameters such as impedance, dielectric constant, tan loss, and conductivity was analyzed using impedance spectroscopy method. The value of the dielectric constant () decreases with increasing frequency and remains constant at higher frequencies. The dielectric loss shows a decrease in the dielectric constant with increasing Mg doping.
