Electrical conductivity and dielectric analysis of La0.75(Ca,Sr)0.25Mn0.85Ga0.15O3 perovskite compound

Study of the electrical and dielectric measurements of a rare-earth doped perovskite La0.6Nd0.1Sr0.3Mn0.7Ti0.3O3

“…The high values of the dielectric constant (e 00 ) observed at low frequencies and especially at high temperatures are also explained on the basis of interfacial/ space polarization due to an inhomogeneous dielectric structure. This behavior is similar to that obtained in [52][53][54]. These inhomogeneities can be porosity and grain structure.…”

Conductivity and giant permittivity study of Zn0.5Ni0.5Fe2O4 spinel ferrite as a function of frequency and temperature

“…We observe an overlap of spectra into a master curve which denotes that relaxation process is irrespective to temperature. In fact, the temperature independency indicates the existence of one relaxation mechanism 35 for all spectra and the merging behavior could be explained by the emission of space charge. 36 Moreover, the value of full width at half maximum is found to be > 1.14 decades indicating a polydisperse non-exponential relaxation.…”

Electrical conduction mechanism and transport properties of LiCrP2O7 compound

“…All the capacitance values (Q 1 ) are in the range of pF corresponds to a bulk capacitance. Moreover, the grain resistance R b decreases with rise in temperature due to the increase of the mobility of charge carriers that adds to the conduction process [23].…”
