Pb-based complex perovskites with Fe³⁺ like Pb(Fe_2/3W_1/3)O₃ were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior. Pb(Fe_2/3W_1/3)O₃ is ferroelectric with ferroelectric Curie temperature T_C 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 (T_C = 1103 K) and antiferromagnetic (T_N = 643 K) ordering simultaneously. The polycrystalline sample of 0.3Bi_0.95Dy_0.05FeO₃-0.7Pb(Fe_2/3W_1/3)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.
