Theoretical description of magnetic structures and PASANS data in ordered arrays of multilayered galfenol nanowires; in collaboration with NIST Center for Neutron Research and University of Minnesota, USA. The results were published in ACS Nano.
Theoretical description of experiments on local ferromagnetic resonance imaging with magnetic resonance force microscopy (FMRFM), has been developed in collaboration with National Institute of Standards and Technology (NIST), Gaithersburg, USA and with George Washington University, USA. The results were published in Physical Review B.
Theoretical explanation of splitting of spin-wave modes in the case of symmetry violation in ferromagnetic wires and circular dots. Theory is in good agreement with experimental data. The results were published in Scientific Reports and in Physical Review B.
A phenomenological theory describing reorientation phase transitions and magnon dynamics in two-dimensional and three-dimensional magnonic crystals (ordered arrays of interacting cylindrical nanowires and nanospheres) has been developed. The theory explains experimental results obtained in George Washington University (USA) and Instituto de Ciencia de Materiales de Madrid (Spain). The main results of this research were published in Physical Review B, Journal of Applied Physics and Journal of Magnetism and Magnetic Materials.
A microscopic theory describing magnetic dynamics in one-dimensional magnonic crystals (multilayers) has been developed. Using the results of this theory, a set of the experiments on neutron facilities in ILL (France) and Helmholtz-Zentrum, Geesthacht (Germany) was planned and realized. The results of the experiments approved quantitatively the theoretical predictions. The main results of this research have been published in Applied Physics Letters and in Physical Review B.
Theoretical description of magnetic properties of FePtRh films and the experimentally observed reorientation phase transitions in such thin films with itinerant magnetism is presented. The results, obtained in collaboration with Helmholtz-Zentrum and Juelich Research Center, Institute for Research on Solid State Physics (Germany), MINT Center, University of Alabama (USA) and Australian Nuclear Science and Technology Organisation (Australia), were published in Physical Review B and Journal of Applied Crystallography.
Theoretical explanations of polarized neutron data on field-induced chirality in rare-earth multilayers; in collaboration with Helmholtz-Zentrum, Geesthacht, Germany. The main results of this research were published in Physical Review B, and Journal of Magnetism and Magnetic Materials.
