•Pure and Pr doped bismuth ferrite (BFO) samples were synthesized by sol–gel technique.•Kirkendall effect plays the important role for reduction in grain size due to doping.•Ferromagnetic, ferroelectric and dielectric properties enhanced with substitution.•The dielectric dispersion explained on the basis of Koop’s theory.•The P–E loops show modification in ferroelectric properties due Pr doping in BFO.
Bi1−xPrxFeO3 samples (0≤x≤0.25 in step of 0.05) were synthesized by the sol–gel technique to investigate the effect of Pr doping on the structural, magnetic and electrical properties of multiferroic bismuth ferrites (BFO). It is observed that Pr doping induces structural changes in BFO and also decreases the secondary phases noticeably. Frequency dependent dielectric properties of pure and doped BFO samples were measured from 300 K to 675 K in the frequency range from 100 Hz to 1 MHz. Enhanced ferromagnetism and improved ferroelectric properties were observed which may be correlated with the structural transformation and grain morphology.
