The goal of the workis the development of physical principles of new generation of magnetic materials for nanoelectronics systems and biotechnology applications.
The authors based on experimental and theoretical investition have determined peculiarities spin dynamics, remagnetization processes and spin waves generation in films and multilayers, nanoelemens and their arrays as well as have studied properties of magnetic nanoparticles and molecular magnets. In particular the possibility of creation of magnetic transistors for information recording and processing, which have low lower energy consumption and higher speed, than existing semiconductor analogous, has been shown. Physical background for creation of microwavegenerators and filters based on metal oxide and all-metal magnonic crystals as well as controlled switchers and gates for electromagnetic radiation of microvave and optical frequency range using periodical structures and metamaterials have been developed. Principles for the creation of small size sensors of electromagnetic radiation and sensors as well as catalysts and sorbents based on organоmetalic molecular magnetics have been developed. Some possibility to use magnetic nanoparticles for directed drugs delivery and biochemical processes control have been studied. Particularly the influence of biogenic magnetic nanopartcles on the processes taking place in living organisms has been cleared up. New type ofmagnonic crystals – dynamical crystals – which are controlled by electric current has been developed.
Physical background of creation of Bi-ferrite-garnet magnetophotonic crystals with double layer active magnetooptical layer was developed. This allows substantial increasing of Faraday rotation in structures with amorphous Bregg mirrors. Methods for chemical reactions control using magnetic fields have been developed. The main applied results have been patented in Ukraine an Sveden.
