Complex studies of the structure and properties of nanosized bodies by X-ray, electron-optical methods. Study of formation mechanisms, structure and physical properties of thin films and compositions based on them, in particular new objects, such as fullerites, quasi-crystals, superlattices, nanocrystals. Identification of structural causes of non-planar magnetic anisotropy in ferromagnetic films and development of methods for its programming. Creation of magnetically soft film materials used for the production of magnetic heads and other electromagnetic devices. Development of film magnetoresistive sensor elements that will be used to detect and measure magnetic fields. Research of strong magnetic fields generated by highly anisotropic permanent magnets, as well as sensors based on nanostructured films with giant magnetoresistance (GMR) to measure these fields. Physics of thin films, phase and structural transformations in nanoscale film compositions. X-ray optics and microscopy. Thermal and radiation stability of x-ray optical elements and systems.
