Magnetoelectric Properties of Zinc-Substituted BiFeO 3 Multiferroics

The magnetoelectric properties of ceramic samples of BiFe1 – xZnxO3 and Bi1 – xZnxFe1 – xZnxO3 multiferroics have been studied in magnetic fields from 0 to 80 kOe at room temperature. All the samples have the linear dependences of magnetoelectric coefficient αME with low hump-like maxima of αME at 10 kHz and also at 85 kHz. These magnetoelectric studies of the bismuth ferrites with doubly substituted Zn show that the double substitution of Zn2+ ions for Bi3+ and Fe3+ ions does not lead to desired enhancement of the magnetoelectric properties as compared with the ordinary substitution of Zn2+.
