The temperature and frequency dependence of dielectric permittivity and dielectric loss of
nanosized Mn1−xZnxFe2O4 (for x = 0, 0.2, 0.4, 0.6, 0.8, 1) were investigated. The impact of
zinc substitution on the dielectric properties of the mixed ferrite is elucidated. Strong dielectric
dispersion and broad relaxation were exhibited by Mn1−xZnxFe2O4. The variation of dielectric
relaxation time with temperature suggests the involvement of multiple relaxation processes.
Cole–Cole plots were employed as an effective tool for studying the observed phenomenon.
The activation energies were calculated from relaxation peaks and Cole–Cole plots and found to
be consistent with each other and indicative of a polaron conduction |
