Effect of Magnetic Field on the Dielectric Properties BaTiO₃-MgFe₂O₄ Composite

In this study we tried to measure the effect of magnetic field on the dielectric properties of BaTiO₃-MgFe₂O₄ soft magnetic composite. Composites with different weight percents of ferroelectric and ferromagnetic phases were subjected to magnetic field in the order of 0 to 450 Oe and the variation of the dielectric properties was observed. The Variation of dielectric polarization was discussed in terms of Maxwell-Wagner type polarization in particulate composites.
