摘要

The growing need of materials for multifunctional devices, the basic sciences and engineering fields are continuously searching and studying the magneto-dielectric materials. Therefore, we are examining the nature of a composite that combines ferroelectric materials with high dielectric characteristics and ferrites with magnetic behaviour. Integrating the distinct properties of these substances can open up various applications. In this research, we focus on the magnetic and dielectric properties of a composite made from perovskite and M-type hexaferrite. The solid state reaction method was used to prepare the composites (1-x) Ba0.98Gd0.02TiO3—(x) Ba0.7Co0.3Fe12O19(where x = 0.05, 0.10, 0.15, 0.20, and 0.25). Phase formation was investigated using Rietveld refinement and presence of two phases has been confirmed. For x = 0.10, the sample has shown the maximum grain size of about 3.68 μm. Magneto-dielectric, structural and magnetic features have all been considered. Through the application of magnetic and electric forces to the materials, this connection between the electric and magnetic realms has been demonstrated in this work. Magnetoelectric coupling was found in all of the prepared substances by magneto-dielectric investigation. With MDR% values of 24.12%, the composition displays the highest coupling for x = 0.20.
