Abstract

The sol–gel prepared (1-x)Na_0.5Bi_0.5TiO₃-(x) CaMnO₃ (x = 0, 0.03, 0.06, 0.12) compositions show a Rhombohedral (R3c) phase up to x = 0.06 while a mixed rhombohedral (R3c) and orthorhombic (Pnma) phases for the x = 0.12. The lattice volume consistently decreased with an increase in the CaMnO₃ content. The phase transition temperature (T_c) decreased with an increase in the CaMnO₃ compositions. The room temperature dielectric constant increased, and loss decreased for the x = 0.03 composition due to a decrease in the oxygen vacancy and Bi loss confirmed by the valence state study (XPS). All the compositions show a variation of the room temperature dielectric property with an application of magnetic field confirming a magnetodielectric coupling. The x = 0.06 composition shows the highest negative magnetodielectric coupling constant (MD%) of 3.69 at 100 kHz at an applied field of 5 kG.
