Essentially new results are obtained: 1. A model of competing magnetic correlations was proposed for BaMn9(VO4)6(OH(2) and proved that this compound may be the newest candidate for a skyrmion-type lattice. 2. A manifistation of magnetoelectric effect in a skyrmion phase of Cu2OSeO3 was revealed in the form of an effective "metallization" of insulator. 3. In the pseudo-Kagome system Cu3Bi(SeO3)2O2(Br,Cl) The role of the distortion of crystal lattice and of the anisotropy of the magnetic exchange on the formation of the main magnetic state and the spectrum of excitations was determinated. 4. Theoretical and experimental study of the magnetic properties and electronic structure of compounds FeTe, SrCouTi (x-y)Fe(12-x)O19 were performed .
