The magnetoelectric polarizability [X, ] of a crystalline material gives rise to a magnetic moment I (Tan axial vector, or T( 1 )ax) when the crystal is placed in an electric field E (Aa polar vector, or T( 1)). Its transpose [T/ ] describes the converse magnetoelectric effect in which the roles of Y and X are interchanged. To find the structure of K = [T, ], we look for IRs which have components of both xy z and Rx Ry Rz as bases. 

If we can combine ferroelectrically polarizable guest molecules with PCPMs, then we can obtain new types of multiferroic materials, where ferroelectricity and ferromagnetism coexist. Such multifunctional materials have recently aroused increasing interest from the viewpoint of the development of new materials with very large magnetoelectric effects. [Mn3(HCOO)6] EtOH is considered to be the first ferroelectric PCP.182 Because the desolvated compound [Mn3(HCOO)6] shows a very small and almost temperature-independent dielectric constant, irrespective of the direction of the electric field,183 the observed ferroelectric property is considered to come mainly from the guest EtOH molecules.

Chromia exhibits the magnetoelectric effect 91-96). This means that it produces a magnetic moment when placed in an externally applied electric field, and, inversely, it produces an electric moment in an applied magnetic field 97,98). 

The essence of magnetoelectric effect is the possibility of appearance of magnetization M induced by electric field E and electric polarization P induced by magnetic field H. For linear magnetoelectric effect (in weak fields)...

In this Chapter, contrary to Chaps. 2 and 3, where primary ferroics were considered, we are going to pay more attention to multiferroics with coexistence of ferroelectric and magnetic order. We will consider these multiferroics in the form of thin films on subsfrate [9, 10] or nanowires [11] on the example of quantum paraelectric EuTiOs. The necessity of detailed consideration of magnetoelectric effects in such systems is pretty obvious also.
