| Abstract: | In response to the growing interest in materials exhibiting magneto-dielectric coupling across diverse application domains, we present a detailed study on the electrical behavior of Ba0.1Bi0.9(Ti0.9Zr0.1)0.1Fe0.9O3 (BBTZF) ceramic. This study includes a comprehensive analysis of temperature- and frequency-dependent dielectric behavior, along with ac impedance properties. The thermo-dielectric study in the temperature range of 300–650 K suggests the presence of an anomaly near the Neel temperature (TN = 603 K), supporting the strong magneto-dielectric coupling in BBTZF. The differential thermal study also revealed an anomaly around TN, characterized by an exothermic peak. Furthermore, the well-described experimental dielectric data as a function of frequency (100 Hz–1 MHz), by the Cole–Cole relaxation equation modified by introducing complex conductivity, demonstrated a remarkable change in the frequency of relaxation (fr) as a function of temperature in the vicinity of TN. This change is attributed to the coupling between magnetic and electric order parameters. Through the complex impedance analysis recorded at different temperatures, it was found that both the capacitance and resistance of the grain showed a change in behavior around TN, suggesting that the magneto-electric coupling is predominantly of intrinsic origin in our material. Furthermore, the intrinsic magneto-capacitance grain value is approximately − 0.36%, highlighting its potential for application in magnetoelectric devices. Finally, the ac conduction study has shown that magnetic ordering can influence the translational hopping of large polaron mechanisms. [ABSTRACT FROM AUTHOR] |
