“…The value of ε r ' decreases with increasing frequency, and then stabilized above 100 kHz. The high value of ε r ' at low frequencies increases with decreasing frequency and increasing temperature may be due to electrode polarization arising usually from space-charge accumulation at the material-electrode interface [9,12]. These are features of dielectric materials [14,9].…”

“…The complex impedance spectroscopy methods have been used successfully for the study of dielectric properties of these materials, which resolves the contributions and relative importance to electrical conduction and/or polarization of different phenomena in the studied frequency region [9][10][11]. The present study has been undertaken to investigate the dielectric studies as a function of temperature and frequency of a LiCo 3/5 Fe 1/5 Cu 1/5 VO 4 system, which has cubic unit cell structure with lattice parameters a = 8.2756 (3) Å, and polycrystalline texture with grains of different sizes ~0.2-3.0 μm [12]. Dielectric properties of this compound have been studied by complex impedance spectroscopy method.…”

In the present work, an evaluation of the relaxation behavior of a system (LiCo 3/5 Fe 1/5 Cu 1/5 VO 4 ) has been undertaken. This system was synthesized by solution-based chemical route. Dielectric measurements were made using complex impedance method. Frequency dependence of real part of dielectric constant (ε r ' ) at different temperatures indicates the features of dielectric materials. Temperature dependence of ε r ' at different frequencies shows the dielectric anomalies in ε r ' at different temperatures. Frequency dependence of tangent loss at different temperatures exhibits dielectric relaxation process in the material. The scaling behavior of tangent loss signifies the similar mechanism for relaxation process at various temperatures.
