dc.description.abstractThere has been a growing interest in multiferroics, materials that combine magnetic and electric ordering, over the past few years. This research investigates the influence of sintering temperature (1075-1175°C for 2 hours) on multiferroic properties of 0.7(0.94Bi<inf>0.5</inf>Na<inf>0.5</inf>TiO<inf>3</inf>-0.06BaTiO<inf>3</inf>)-0.3(Ni<inf>0.7</inf>Zn<inf>0.3</inf>Fe<inf>2</inf>O<inf>4</inf>) (BNT-BT-NZF) multiferroic composites, fabricated using solid-state combustion with glycine as a fuel was investigated. The XRD patterns of all ceramics revealed the coexistence of a rhombohedral ferroelectric phase, a tetragonal ferroelectric phase, and a cubic ferromagnetic phase. The average grain size, dielectric constant (ε<inf>r</inf>), dielectric loss (tanδ), remnant polarization (P<inf>r</inf>), and coercive field (E<inf>c</inf>) tended to increase from 0.66 to 2.5μm, 314 to 829, 0.22 to 0.51, 0.36 to 5.82 μC/cm<sup>2</sup>, and 7.05 to 26.96 kV/cm, respectively, with increase of sintering temperature. The composite ceramics exhibited peak saturation magnetization (M<inf>s</inf> ~ 12.21 emu/g) and magnetoelectric (ME) coupling (~ 3.59 mV/cmOe) when sintered at 1150°C.
