Asymmetry of superconducting gap dispersion in e- and h- doped cuprates.

The dependence of the superconducting gap on the wave vector contains important information on the nature of the Cooper-pairing mechanism. The measurements with increasing accuracy provide grounds for the inclusion of higher harmonics with the d wave symmetry in the gap dispersion for both hole- and

Magnetoelectric coupling in noncollinear ferrimagnets

The analytical expressions for the magnetoelectric coupling derived using perturbation theory, combining the action of odd crystal field, spin?orbit and exchange interactions. Mainly I will focus on FeV2O4 and LiCu2O2 .

Toward the Theory of the Coupling Sins and Orbital Moments with Electric Field

I revisit the theory of interaction of the spins and orbital moments with electric field focusing on the transition metal compounds without inversion symmetry. As specific examples, I will discuss the terahertz absorption spectrum of Fe2+ in tetrahedral environment, optical absorption of Cu2+ ions i
