Structural and dielectric properties of LaFeO3 orthoferrite ceramics.

LaFeO3 orthoferrite perovskite is synthesized by conventional solid-state reaction method. The structural properties of the sample is studied through X-ray Diffraction (XRD) which indicates an orthorhombic structure with lattice parameters "a" =5.5560 Å, "b" =5.5650 Å and "c" =7.8620 Å at room temperature. The Dielectric constant(εr)and tangent loss(tanδ) of the above ceramic compound are studied over a temperature range 25°C-380°C with different frequencies. The different dielectric values with frequency and temperature have been provided. [ABSTRACT FROM AUTHOR]
