Discovery of the Phenomenon of Magnetic Field Inducing of Phases Concealed in the Field of Negative Pressures. Discovery of Meta-stable Hetero-phase States in Magneto-electrics. Investigation of the Peculiarities of the Magnetic Ordering and Phase Transitions in Magnetics with Some Order Parameters. Investigation of Phase Transitions in the Crystals with a Position Disorder.
The School of nanophysics and nanotechnology.
The founder of the school is Viktor N.Varyukhin, corresponding member of NAS of Ukraine. The basic results recognized in the world:
A method for production of bulk nanocrystal materials has been developed, namely, twist extrusion. The methods for obtaining nanocolumnar and nanoglobular carbon-based films characterized by unique optical properties have been realized. Nanoscale phase separation of co-existing ferromagnetic and antiferromagnetic areas has been found in manganites of rare-earth metals characterized by giant magnetoresistance. The existence of superconducring areas (drops) of condensate of Cooper pairs has been found in high-temperature superconductors at the temperatures above the temperature of the superconducting transition. Physical basis for formation of hybrid and composite nanomaterials and their properties by application of high pressure and severe plastic deformation has been developed. Invar effect, that is a hundred times lower coefficient of thermal expansion, has been achieved in the samples of semicrystalline polymers due to formation of a specific nanostructure by the applied severe plastic deformation with shear.
