The structural, Electrical, and Magnetic properties of perovskite ceramics Ba0.997La0.003Ti1−xGdxO3 \((0\,\text{ mol\%}\le \text{x}\le 5\,\text{ mol\%})\) were investigated. A tetragonal to cubic phase transition was observed. The maximum saturation magnetization and the highest permeability with the lowest magnetic loss tangent at room temperature were observed for Gd content of x = 1 mol%. The maximum dielectric constant with high resistive behavior at the low-frequency regions is found for Gd content of x = 1 mol%. The sample with Gd content x = 2 mol% shows good magnetic, and ferroelectric properties, and the highest dielectric constant with the lowest dielectric loss tangent at the high-frequency regions. Therefore, Ba0.997La0.003Ti1−xGdxO3 with x = 1 mol%, and x = 2 mol% will be promising templates for high-performance memory devices, spintronics, actuators, magnetic field sensors, and switches due to the better dielectric, ferromagnetic, and high resistive behaviors.
