Mn1−xZnxFe2O4 nanoparticles (x = 0 to 1) were synthesized by the wet chemical
co-precipitation technique. X-ray diffraction and transmission electron microscopy and high
resolution transmission electron microscopy were effectively utilized to investigate the
different structural parameters. The ac conductivity of nanosized Mn1−xZnxFe2O4 were
investigated as a function of frequency, temperature and composition. The frequency
dependence of ac conductivity is analysed by the power law σ(ω)ac = Bωn which is typical
for charge transport by hopping or tunnelling processes. The temperature dependence of
frequency exponent n was investigated to understand the conduction mechanism in different
compositions. The conduction mechanisms are mainly based on polaron hopping conduction |
