Exploration through Structural, Electrical, and Magnetic Properties of Al3+ Doped Ni–Zn–Co Nanospinel Ferrites

“…41 This short-range charge carrier mobility under the induced electric fieldʼs influence may occur because of restoring force deficiency inside the samples' sublattices. 42 Moreover, asymmetric peaks at higher frequencies indicate space charge separation for all of the ferrite samples. The variation of maxima confirms the differences in space charge polarization with compositions x.…”

“…46 The existence of a single semicircle in all of the ferrites indicates that the influence of the grain boundaries is more prominent than the outcome of grains in the conduction process. 42,47 Co(NO 3 ) 2 •6H 2 O, Fe(NO 3 ) 2 •9H 2 O, and Al(NO 3 ) 2 •9H 2 O] obtained from Merck, Germany, with 99.98% purity were measured according to the stoichiometric ratio and preserved in a beaker. Ethanol (50 mL) was substituted and stirred in a magnetic stirrer at a constant speed (300 rpm) for 1 h at room temperature for melting the nitrates to make the solution.…”

“…The short-range mobility charge carrier’s conduction process is responsible for the continuous dispersion with increasing frequency . This short-range charge carrier mobility under the induced electric fieldʼs influence may occur because of restoring force deficiency inside the samples’ sublattices . Moreover, asymmetric peaks at higher frequencies indicate space charge separation for all of the ferrite samples.…”

Synthesis, structural and electrical characterization of a new organic inorganic bromide: [(C3H7)4N]2CoBr4

“… 29,41 This behavior confirms that the relaxation is non-Debye type (single relaxation time). 42 Fig. 13 shows the complex modulus spectrum ( M ′′ versus M ′) of [TPA] 2 CoBr 4 at selected temperatures.…”

Low sintering effect on structural, electrical and magnetic properties of rare-earth metal ion Er3+-substituted nickel–zinc spinal ferrites

“…11a, the real electric modulus (M 0 ) increases with the frequency increase and shows the presence of dispersion at higher frequencies. The low values at the low-frequency side and the occurrence of dispersion at the higher-frequency side might be assigned to the conduction mechanism due to the mobility of charge carriers in a sort range, and these interpretations may also be associated with a deficiency of restoring force that dominates the mobility of charge carriers under the action of an induced electric field [36,37]. The imaginary part of electric modulus (M 00 ) is depicted in Fig.…”
