Pb-based complex perovskites with Fe3+ like Pb(Fe2/3W1/3)O3 were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior. Pb(Fe2/3W1/3)O3 is ferroelectric with ferroelectric Curie temperature TC between 150 and 200 K and at the same time is antiferromagnetic with magnetic Néel temperature about 400 K. BiFeO3 is a well known perovskite compound which exhibits ferroelectric (TC = 1103 K) and antiferromagnetic (TN = 643 K) ordering simultaneously. The polycrystalline sample of 0.3Bi0.95Dy0.05FeO3-0.7Pb(Fe2/3W1/3)O3 were synthesized using standard sintering procedure. Magnetization vs. magnetic field (at 4.2 K) curves were measured. Magnetoelectric properties of the sample were obtained.
