Magnetoelectric interaction phenomena in materials

Abstract

Following the phenomenological approach of Landau and Lifshitz the existence of linear magnetoelectric effect in antiferromagnetic Cr 2 0 3 was predicted by Dzyaloshinskii which was later experimentally confirmed by Astrov and Folen et al. Magnetoelectric phenomenon has been observed in several single-phase materials in which simultaneous electric and magnetic ordering coexists and in two-phase composites in which the participating phases are the ferroelectric and magnetic. The author's group has recently undertaken a systematic study of the preparation, characterization and detection of the (ME)n output in a few single-phase materials and two-phase composites. This article describes the magnetoelectric phenomenon in general and recent work carried out in the author's group.

Recent advancements in magnetoelectric particulate and laminate composites

“…Suryanarayana has reviewed the ME effect for the family of compounds represented by the general formula Bi 4 Bi m−3 Ti 3 Fe m− 3 O 3m+3 , where compounds with m=4, 5, 6, 7 and 8 have been successfully synthesized [14,15]. The maximum magnitude of the ME coefficient for Bi 5 FeTi 3 O 15 was found to be 17 mV/cm·Oe under a DC bias of 8,000 Oe; while for Bi 6 Fe 2 Ti 3 O 12 , it was 3.2 mV/cm·Oe under 4,000 Oe [14,16].…”

Impedance spectroscopy and dielectric behavior in barium strontium titanate–nickel zinc ferrite composites

“…When ferromagnetism and ferroelectricity coexist in a material, magnetic-electric effect phenomena are expected due to the interaction between the magnetization and the electric polarization [3][4][5]. There are very few single-phase materials with such combined properties [6].…”
