“…This confirms that the conduction phenomenon in these composites is due to small polaron hopping. Similar results have also been reported by other researchers [36,40,41]. The variation of s AC with frequency can also be explained on the basis of Jonscher's law [42]:…”

“…The frequency dispersion of dielectric loss is observed both in the low and high frequency regions. Similar behavior has been observed in the dielectric loss vs frequency plots for ferroelectric-ferrite composite by Rahman et al [36]. At high frequencies, the dielectric loss decreases due to the suppression of domain wall motion.…”

“…As the ferrite content increases beyond 20% mismatching between the grains increases due to the large difference in grain size of the two phases and hence α ME decreases. The values of α ME of the present composites are found to be higher than reported by other researchers [13,18,36,[52][53][54][55].These ME composites provide opportunities for potential applications as multifunctional devices such as microwave devices, sensors, magneticelectric transducers, gyrators, phase shifters, heterogeneous read/write devices and sensors.…”

“…3b. It is found that for all three samples the AC conductivity (r AC ) increases with increasing frequency; however, the AC conductivity plots are not exactly linear which indicates that the conductivity occurs by hopping of mixed (small and large) polaron type of charge carriers among the localized states [23]. In the low frequency region dispersion is observed in the conductivity curves in which the grain boundaries are more active whereas the role of polaron hopping process is negligible.…”

Multiferroic composites of (1 -x)PbZr 0.52-Ti 0.48 O 3 ? (x)CoFe 2 O 4 with x = 0.0, 0.15, 0.30, 0.45 and 1.0 are synthesized by using ball milling method. Rietveld refinement of XRD patterns confirmed the single phase formation in x = 0.0 and x = 1.0 and two distinct phase formation in x = 0.15, 0.30 and 0.45 composites. SEM images explored the effect of CFO content on the grain connectivity of each phase in the prepared composites.The dielectric properties showed dielectric dispersion with increasing frequency due to interfacial polarization; whereas the dielectric constant is found to increase with increasing CFO content which is attributed to the space charge effect. AC conductivity analysis suggested the mixed polaron hopping type of conduction mechanism. Magnetic hysteresis loops exhibited ferromagnetic like behaviour, indicating the presence of ordered magnetic structure in the prepared composites. Furthermore, with increasing CFO content, the saturation magnetization, magnetostriction and strain sensitivity is found to be increased which in turn have a significant effect on the magnetoelectric coefficient. The maximum magnetoelectric coefficient of 1.45 mV cm -1 Oe -1 is obtained for x = 0.30 composite. Here, the observed variation in the magnetoelectric coefficient is correlated with the microstructure as well as the amount of CFO content.

A series of nanocomposites with a chemical formula of (1−x) (Al0.2La0.8TiO3) + x (BiFeO3)/ALTBF is prepared through low temperature hydrothermal method. The tetragonal phases are detected at x = 0.2 and the x = 0.4–0.8 composites show the existence of cubic phases. The transmission electron microscope pictures show the presence of well‐defined spherical particles for all composites. Furthermore, photocatalytic activity is observed for x = 0.2–0.8 composites during time intervals ranging from 0 to 240 min. The x = 0.2, 0.6, and 0.8 nanocomposites reveal the usual behavior of ac‐electrical conductivity (σac), dielectric modulus parameters (M′ and M″), and impedance parameters (Z′ and Z″). However, interestingly, x = 0.4 composite performs the negative values of electrical parameters like σac, M′, M″, and Z″. This implies that x = 0.4 composite behaves like a metamaterial possessing negative indexed electrical parameters. Therefore, x = 0.4 composite can be well suited for microwave device applications at high frequency.
