Magnetoelectric Effect in Magnetic Materials

Abstract

Magnetoelectric effect in magnetic insulators is reviewed. Alter an intuitive explanation of the effect in antiferromagnetic Cr 2 O3, the following topics are discussed on the experiments. Measurement and controlling of antiferromagnetic domains as well as antiferromagnetic domain wall motion. Expansion of the free energy of crystals in terms of magnetic and electric fields and polarizations. Information on the magnetic symmetry of crystals. Investigation of mechanisms of magnetoelectric effect. Excited states and optical observation.

Tables of the Second Rank Constitutive Tensors for Linear Homogeneous Media Described by the Point Magnetic Groups of Symmetry

“…In physics, the magnetoelectric effect is considered usually in magnetic crystals [20,27,28], and Tables of the magnetoelectric polariz-ability tensors for magnetic crystals can be found for example in [20,27,28,41,58]. However, most of our results for the magnetoelectric tensors for 58 groups of the third category are in disagreement with those in Table 9 of [27, Table 9, pp.…”

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].…”

Designing switchable near room-temperature multiferroics via the discovery of a novel magnetoelectric coupling

“…Numerous studies [8][9][10][11][12][13][14][15][16][17][18][19] have been performed to investigate various types of ME couplings in multiferroics. Within the Landau theory, the macroscopic free energy of the ME coupling can be expressed in terms of the ferroic orders including the polarization P , magnetization M, antiferromagnetic vector L, antiferroelectric vector A and so on.…”
