Description
Summary: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.
