The magnetic, optical-spectral and ferroelectric properties as well as the domain structure and magnetoelectric interactions in the most prospective for practical applications ferroics were investigated. For the first time the domain structure in (CH3)2CHNH3]4Cd3Cl10 was visualized and the peculiarities of the ferroelastoelectric ordering were explained. The models describing the nature of the magnetic ordering and magnetic properties of [(CH3)3NH]MnC13×2H2O and (N(C2H5)4)2CoCl2Br2 were proposed. The ferroelectric phase and spontaneous magnetoelectric effect has been found in (N(C2H5)4)2CoCl2Br2 crystals and the model describing the ferroelectric ordering was proposed. The obtained experimental results concerning the magnetic properties of [(CH3)3NH]MnC13×2H2O and (N(C2H5)4)2CoCl2Br2 and the ferroelectric properties and magnetoelectric interactions in the latter crystal were confirmed by the data of computer modeling with employing of the DFT model. It has been shown that NH2(CH3)2Ga0.935Cr0.065(SO4)2×6H2O crystal is characterized by a very strong magnetodielectric effect as well as the considerable influence of magnetic field on the spontaneous polarization. The model describing the magnetoelectric interactions in this crystal was proposed. The method of manufacturing of the thermochromic microcomposite on the basis of NH2(C2H5)2)2CuCl4 for thermography was developed.
