Magnetoelectric Properties of 0.3Bi0.95Dy0.05FeO3-0.7Pb(Fe2/3W1/3)O3Multiferroic

Pb-based complex perovskites with Fe 3+ like Pb(Fe 2/3 W 1/3 )O 3 were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior.Pb(Fe 2/3 W 1/3 )O 3 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. BiFeO 3 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 0.95 Dy 0.05 FeO 3 -0.7Pb(Fe2/3 W 1/3 )O 3 were synthesized using standard sintering procedure.Magnetization vs. magnetic field (at 4.2 K) curves were measured.Magnetoelectric properties of the sample were obtained.
