This report is final, it includes essentially a report for the II. stage of this topic (for 2021). The introduction to it, Section 1, describes the structure of the Report. Section 2 describes the study of magnetic elastomers (MAE), in particular the phenomenon of bending the rod with MAE in a transverse magnetic field. It is substantiated that the critical bending behavior is due to the magnetic and magnetoelastic properties of these compounds. The shape memory effect was found in them. Section 3 describes studies of the structure and electrical properties of multilayer recovered graphene oxide. It is established that this material is a system of graphene areas separated by carbon barriers. Its conductivity is characterized by Coulomb blockade and jumping conductivity. Section 4 is devoted to the study of the thermomagnetic effect in a spintronic structure of the spin valve type. It is shown that it mainly depends on the multilayer magnetic structure of the sample and its transformation in the applied magnetic field. The issue of domain wall dynamics in chiral antiferromagnets is the main subject of Section 5. Studies of the dynamics of soft phonon modes in ferroelectrics using scanning probe microwave microscopy are the subject of Section 6. Theoretical researches on this issue have been compared to an experiments which had been performed by foreign co-authors. Section 7 contains a brief description of the findings effect of the dependence of the energy of indirect excitons in the double quantum well on the excitation energy. Based on the materials of this stage, 7 articles were published [1 * -7 *], two of them are still under publication.Two paper had been reported [8 * - 9 *] at scientific conferences. All articles are published in journals indexed by Web of Science and / or Scopus.
