Theoretical investigations of magneto-electric phenomena

Magneto-electric phenomena (the appearance of electric polarization in magnetic field and the induction of magnetic moment by electric field) have a large fundamental and practical scientific significance. These phenomena open the possibilities to change the magnetic (electric) properties by electric (magnetic) field and may be used for the creation of a multifunctional elements in a wide frequency region from SH frequency to optical one.

Different manifestations of magneto-electric (ME) interactions in thermodynamic and high frequency properties of the crystals with spontaneous magnetic and ferro (antiferro) electric ordering were investigated. Some ME experimental phenomena (the jump of electric polarization by spin-flop, temperature anomalies of ME susceptibility in the boracites, etc.) were explained and new possible ME effects were predicted. These results are the subjects of more than 80 manuscripts and of 7 monographs:

The influence of dynamic ME interactions on phonon polariton spectrum of an insulator at the boundary with a metal in the presence of constant electric and magnetic fields of definite directions was investigated. It was shown that the field of electromagnetic wave is pushed out from the volume to the surface of an insulator by toroidal excitations. Strong nonreciprocity of phonon polaritons appears in the presence of a constant magnetic field: polariton of a given frequency of IR or optical regions propagates only in one direction (Chupis I.E. and Mamaluy D.A.).

Last time thermodynamic and  high-frequency properties of the ferroelectromagnet TbMnO₃ were investigated. The excitations of electromagnons by alternating electric field, polaritons in the TbMnO3 at the boundary with a metal in magnetic field, domain nonreciprocity of electromagnetic waves were analyzed. Magnetic phase diagrams and the reason of so called electric polarization flop” were revealed.
