LOCALIZED CARRIERS, ORGANIC CONDUCTORS, SOLAR ELEMENTS, DISC DIELECTRIC RESONATORS, MILLIMETER WAVES. The object of research is the phenomena and processes of interaction of electromagnetic resonance radiation of GHz frequency range, which is formed in dielectric resonators, with the surrounding environment. The aim of the research is to develop a non-contact radiophysical method for studying the spin dynamics and transport properties of spin carriers in organic conductors using high-quality disk dielectric resonators (DDR). This thechnique, in which triplet excitons in the studied organic conductors are associated with the microwave field of the dielectric resonator, will simultaneously probe the length of the photoexcitation and investigate the characteristics of their spin properties using spin resonance. The use of highly sensitive dielectric resonators will expand the range of measurements to the temperature range from ultra-low temperatures to room temperature (1.5 K – 300 K) and magnetic fields up to 10 T. According to the work plan, modernization of measuring stands and low-temperature radiospectrometer "Tornado" was carried out. The spectral, energy and field characteristics of disk dielectric resonators and excitatory elements have been studied. Taking into account the design of cryogenic equipment available to French researchers, sketches of an electrodynamic unit with a resonant cell in the form of a disk dielectric resonator were developed to study the spin dynamics and transport properties of spin carriers in organic conductors. A joint article based on the results of the work is being prepared: V. Derkach, R. Golovashchenko, A. Shepelanski. “Investigation of spin dynamics and transport properties of spin carriers in organic conductors using disk dielectric resonators”.
