Abstract

<jats:title>Abstract</jats:title><jats:p>Sr<jats:sub>1-x</jats:sub>Gd<jats:sub>x</jats:sub>TiO<jats:sub>3</jats:sub> (0.00 ≤ x ≤ 0.11) ceramics by the addition of Gd<jats:sup>3+</jats:sup> on A-sites, were processed and fabricated through the conventional sintering method and optimised the sintering temperature at 1390 °C–1470 °C for 2 h. The experimentation shows that all ceramics are possessed by cubic structure, in which the increment of Gd<jats:sup>3+</jats:sup> content, in terms of x, decreases the lattice parameters of the ceramics, as well as affects the grain size. Comparing the results to pure SrTiO<jats:sub>3</jats:sub> (STO) compounds, the addition of Gd<jats:sup>3+</jats:sup> lowers the mass loss, increased the conductivity as well as permittivity by decreasing the dielectric losses at lower frequencies. The x = 0.03 and 0.01 evidenced the maximum Seeback Coefficient, ∼281 <jats:italic>μ</jats:italic>V K<jats:sup>−1</jats:sup> at ∼370 K confirming the higher carrier concentration. Also, the magnetic properties as a function of Gd<jats:sup>3+</jats:sup> ions doped with STO showed gradual improvement, showing maximum saturation with the maximum concentration of x.</jats:p>
