The advantages of these methods over the diffraction methods come to light in investigation of the structure of small second-phase precipitates, amorphous, X-ray amorphous, nanocrystalline materials, the initial stages of atomic ordering as well as of the processes of atom redistribution in materials with similar electron and/or nuclear factors of scattering of components, etc. He has established theoretically the relationship between the effective magnetic field strength on nuclei of resonant isotope atoms and z-components of nodal magnetic moments in ferromagnetic impurity crystals of transition metals (1982). This allowed him to suggest a new (as an alternative to neutron diffraction analysis) method of determining individual magnetic moments of atoms by the magnetization data and the Mossbauer effect and establish z-components of magnetic moments for a large number of impurities of 3p-, 4p-, 5p-, 3d-, 4d- and 5d- elements in iron. Jointly with colleagues (1989), he discovered and gave a theoretical justification to a new type of radiation-induced self-propagating phase transformations in condensed matter, similar to the combustion and detonation phenomena. He was the supervisor of a joint Russian-German project on the development of advanced methods of ion-beam modification of metals and alloys (2002-2004) carried out within the scope of an inter-governmental agreement.
