Impedance and modulus spectroscopic studies on 40PrTiTaO6 + 60YTiNbO6 ceramic composite

Temperature and frequency dependent conductivity and electric modulus formulation of manganese modified bismuth silicate glasses

“…13(a) and (b) show the real and imaginary parts of electric modulus, M′ and M″, respectively, as a function of frequency at various temperatures. For the presently studied glass system, M′ shows the general trend as observed for many other disordered materials [21,44,45] i.e. for each temperature, M′ reaches a constant value at high frequencies.…”

Characterizations and electrical properties of ZrTiO4 ceramic

“…11(b) shows the resolved semicircles and their equivalent parallel RC elements of the 200 8C Cole-Cole plot. A depressed semicircle whose center lies below the positive real axis suggests its departure from the ideal Debye behavior [38]. In general, the semicircle at the high frequency end refers to bulk electrical conduction, the intermediate semicircle corresponds to conduction by the grain boundaries and semicircle at the low frequency end arises from electrode process.…”

Synthesis, crystal structure, thermal analysis and dielectric properties of (C 8 H 12 N) 3 SnCl 6 .Cl compound

“…At lower frequencies the value of M 0 appears to zero. This negligible value indicates that the electrode polarization have a negligible contribution to (M*) and the dispersion is mainly due to conductivity relaxation [39,40]. M 0 attains a maximum at high frequency side for all temperatures.…”
