Abstract
The electrical conductivity (σ) and thermopower (Q) of Li-Ni mixed ferrites have been studied as a function of composition and temperature. The conduction mechanism in these ferrites has been explained with the help of carrier concentration (n) and charge carrier mobility (μ) calculated from the measured experimental values. The composition and frequency dependence of dielectric constant (ε′) and dielectric loss tangent (tan δ) have also been studied at low frequencies. A relationship between dielectric constant (ε′) and electrical resistivity (ρ) has been arrived at. A qualitative explanation for observing a maximum in the plots of dielectric loss tangent and frequency has also been given.This publication has 9 references indexed in Scilit:
