Karazin Kharkiv National University popup.description2  The object of research is the low-dimensional magnets based on ion-radical compounds of transition metals. Purpose - Synthesis of new ion-radical salts with electrical and magnetic characteristics sensitive to the changes in the chemical environment. Research methods - electrosynthesis, X-ray diffraction analysis, resistive measurements, spin formalism of the valence bond method, analytical methods of quantum solid state theory. As a result of the implementation of the project stage, new coordination compounds of Copper(II) and Cobalt(II) were synthesized and their crystal structure was investigated. A number of polynitrogen-containing heterocyclic complexones were synthesized using click chemistry methods and the effectiveness of the corresponding synthetic approaches was analyzed. It has been proven that CORSA mineral substance can be used to extract radionuclides 90Sr and 137Cs from neutral water environments. The existence of quantum phase transitions for the ground singlet state of infinite frustrated two-link ladder, mediated by the value of the interaction between neighboring rungs, is proved. Using the renormalization group method in the formalism of the density matrix and the quantum Monte Carlo method, the existence of an intermediate plateau in the magnetization profile of composites based on graphene clusters and complex compounds of transition metals is shown. With the help of strict quantum theory, the effects of interaction between the spin, electric and elastic subsystems of spin-chain systems were studied.
