ABSTRACT The magneto-dielectric properties can be tuned through ferromagnetic–ferroelectric composites with different Mn0.9Zn0.1FeO4 to BaTiO3 ratio. The two phenomena can couple and interact with each other when they exist simultaneously due to induced electric polarization in the magnetic order. The composites were synthesized using the nanoparticles of Mn0.9Zn0.1Fe2O4 and BaTiO3 with different composition by sintering at 1000°C. The X-ray diffraction confirms the coexistence of ferromagnetic and ferroelectric phases. The surface micrographs show variations in the porosity along with two types of inter grain connectivity. The magnetic and ferroelectric hysteresis loops confirm the magneto-electric coupling presents in the composites.
