The functional properties of titanium-doped bismuth ferrite (Bi0.05Ti0.05FeO3)(x = 0.05) are synthesized in nanophase using the Sol–gel process. The rhombohedral single-phase structure is confirmed in titanium-doped bismuth ferrite and is demonstrated using XRD. For two distinct temperatures, the average crystalline size falls between 33 and 37 nm. The metal oxide bond present below the range 400–600 cm−1 confirms the presence of a perovskite-type structure. Magnetic behaviour is determined using M-H loops from VSM analysis. Ti ion substitutions for regulated magnetic properties of bismuth ferrite are made possible by the material's intrinsic magnetic properties. The dielectric constant increased, but the loss tangent decreased with concerning dopant. The Arrhenius plots demonstrate that AC conductivity increases with increasing temperature for a specific frequency of approximately 104 Hz. The present work is to determine how these variations in the titanium-doped bismuth ferrite nanoparticles, with two different increasing temperatures, also have better dielectric qualities.
