Samarium (Sm) doped modified bismuth ferrite samples Bi1-xSmxFeO3 (x = 0, 0.02, 0.05, 0.08, 0.1) were prepared by sol-gel technique. A detailed study on the electrical and magnetic properties of the samples was analyzed. X-ray diffraction patterns confirm the formation of the pure phase rhombohedral structure of bismuth ferrite. The dielectric constant (epsilon) and loss tangent (tan delta) show the large frequency dispersion at low frequency. AC conductivity was enhanced with Sm substitution of Bi sites. The enhancement in the ferroelectric properties was delineated by Polarization-Electric field (P-E) loops. Sm substitution of Bi improves the saturation magnetization and magneto-dielectric coefficients.
