Barium zirconate titanate is a very promising material having good ferroelectric properties while bismuth ferrite is a well known multiferroic material. In the present work, the compounds (1 − x) Ba Zr0.025Ti0.975O3–(x) BiFeO3 (x = 0.1–0.4) have been synthesized using solid state reaction method and structural analysis reveal the formation of single phase solid solution. Initially, the Curie temperature increases with increasing bismuth ferrite up to x = 0.2 and with the further increase in bismuth ferrite content, the Curie temperature decreases. There is an increase in the value of dielectric constant at 1 kHz from 551 for x = 0.1 to 3509 for x = 0.4 at their Curie temperatures. The values of coercive field decrease with the increasing bismuth ferrite content resulting in slim ferroelectric loops which confirms the formation of relaxor multiferroics.

► The compositions (1 − x) BZT-x BFO (x = 0.1–0.4) have been synthesized using SSR.
► The samples showed Relaxor behavior with the increasing concentration of BFO.
► Single phase at higher conc. of BFO has been justified through Defect Equation.
► The relaxor behavior has been supported by the slim ferroelectric loops.
