Abstract
- Dielectric properties such as dielectric constant (ε′) and dielectric loss tangent (tan δ) of Li<subscript>0.5+x</subscript>Fe<subscript>2.5-2x</subscript>Sb<subscript>x</subscript>O<subscript>4</subscript> ferrites, 0.10≤ x ≤0.30 in steps of 0.05 have been investigated as a function of composition, frequency and temperature. The dielectric constant showed dispersion with frequency in the range of 100 Hz–1 MHz. Peaks were observed in the tan δ versus frequency curves for almost all the samples. The temperature variation of dielectric constant for the different samples was studied at 10 kHz in the temperature range from room temperature to 433 K. Peaks were observed for some of the samples. The peaks were seen to shift towards higher temperature region as the substitution level increases. The mechanisms involved in the processes are discussed in this paper. [ABSTRACT FROM AUTHOR]
