Abstract :

Dielectric materials are having an active role in satellite communication system. These materials are key for development of
the low-loss and temperature stable resonators and filters for the communication. High dielectric constant is required for
miniaturization of wireless systems. Nowadays, Perovskites structure related materials are being studied for this application.
Li2SrNb2O7 compound was synthesized by conventional solid state reaction method. This compound was found to crystallize in
orthorhombic structure at room temperature. The structure of this compound belongs to the Ruddlesden-Popper (RP) structure.
The phase transition in the Li2SrNb2O7 compound was studied with the help of Raman spectroscopy.
