Structural, dielectric and electrical properties of LiBaFeWO6

The polycrystalline sample of LiBaFeWO6 was prepared by a high-temperature solid-state reaction technique. Preliminary structural analysis shows the formation of a new compound with an orthorhombic crystal structure at room temperature. The SEM micrograph shows the polycrystalline nature of the sample with different grain-size and inhomogeneous distribution. The temperature dependent dielectric and impedance behavior of the material was studied in a wide frequency (1 kHz-1 MHz) and temperature (30-480 °C) range. The nature of electrical conduction and relaxation is supported by hopping mechanism of ions and oxygen vacancies.
