Abstract: | We investigate the dielectric relaxation and magnetodielectric (MD) properties of the (1-x)Bi5Ti3FeO15/(x)Bi2Fe4O9 (x = 0.0 and 0.3) composites. The sample is prepared by the sol-gel method to study its physical properties. The existence of mixed phases in the composite is assured by the Rietveld refinement of the XRD pattern. The dielectric data at different frequencies reveals the dispersive behavior of the pure cum composite samples. The εʹ vs. temperature reveals the appearance of relaxation behavior around 170 K in the composite. The frequency variation of the εʹʹ study excludes the Maxwell-Wagner origin of the dielectric relaxation. Further, the modified Curie-Weiss law analyzes the relaxor nature of the composite. The magnetic field-dependent MD% shows the maximum strength in the highly dielectric dispersive region. The maximum strength of MD effect ~0.2% is found in composite at 300 K. |
