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

“…But as the frequency increases, the conductive grains become more active, generating electron hopping between the grains. 34 Thus, conductions occur inside ferrite samples and resistivity displays a decreasing trend with higher frequencies. The dispersion of resistivity occurs in the low-frequency area because of cation concentration differences inside the samples' sublattices.…”

“…34 The conducting grains inside the samples are enclosed by the highly resistive grain margins. 34 The hopping carriers pile up across the barriers at low frequencies and hinder the conduction of electrons between the grains. 34 Hence, ferrites act as a high resistive material in the low-frequency regime.…”

“…All of the samples’ ac resistivities decrease with increasing frequencies and progress independently in the high-frequency zone. The Maxwell–Wanger double layer model for ferrites can interpret the samples’ resistive manner with frequencies . The conducting grains inside the samples are enclosed by the highly resistive grain margins .…”
