Sr1-xGdxTiO3 (x=0.00-0.11) ceramics by the addition of Gd3+ on A-sites, were fabricated by adapting the conventional solid-state reaction method by optimising the temperature for sintering at 1390-1470ᴼC for 2hrs. The experimentation shows that all ceramics have pure cubic structure, which the addition of Gd3+ decreases the lattice parameters and grain sizes. Comparing the results to pure SrTiO3 compounds, the addition of Gd3+ lowers the mass loss, increasing 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 µV/K at ~370 K confirming the higher carrier concentration. Also, the magnetic properties as a function of Gd3+ ions doped with Strontium Titanate showed gradual improvement, showing maximum saturation with the maximum concentration of x.
