In particular, magnetic elastomers, compounds with a very elastic matrix filled with magnetic particles, were studied. In such systems, the forces of the magnetic dipole-dipole interaction between the particles are sufficient to affect the elastic parameters and the external shape of the samples, their linear elongation in the direction of magnetization. These systems are already beginning to be implemented in robotics. The planned studies have been performed and their main results are described in Section 2 of this report together with studies of magnetic nanopowders and nanogranular composites in the form of thin films. The Brief Introduction to the Report is numbered as "Section 1". The plan also provided for the study of low-dimensional strong magnetic materials and their nonlinear properties, in particular those related to the domain structure, and their control by changing the magnetic moments by electric current to create devices for practical use. The results of these studies are described in section 3 of the report. In terms of the properties of ferroelectrics, a study of the mechanism of influence on their parameters of modification of the composition of the samples by adding rare-earth impurities. These studies are mostly theoretical. Their main content is described in Section 4. For the convenience of the report, the figures and formulas of each section have a "double" numbering, such as "N.M" where N is the section number and M is the number of the corresponding object (figure, formula) in this section. The results of the project can be used to create functional elements based on nanogranular films, in particular for magnetic hyperthermia, magnetoelastomers, and devices using ferroelectric compounds, in further research at the IF NASU and other research centers, both in Ukraine and abroad outside Ukraine and in the learning process Product Description popup.authors Bodnaruk Andriy V Bondar Oleksandr V Kalita Viktor M Kovalchuk Denis G Kulyk Mykola M Lozenko Albert F Morozovska Anna M Ryabchenko ; Sergiy M Terletskiy Oleg V Chornomorets Nadija F popup.nrat_date 2021-01-29 Close
