Outline of Final Research Achievements

Magnetoresistance measurements show that the organic superconductor k_H_(DMEDO-TSeF)_2_[Au(CN)_4_](THF) has weak interlayer interaction, i.e., an incoherent electronic system. This is due to the arrangement of the polar molecule THF. The Fermi surface of the organic superconductor ka'2-(BEDT-TTF)_2_Ag(CF_3_)_4_(TCE) composed of the superconducting and the charge ordered layers has been observed. The organic superconductor (BEDT-TTF)_2_Cu(CF_3_)_4_(TCE) has two phases, high-Tc and low-Tc phases. The crystal structure of the high-Tc phase has been unknown since 1994. The crystal structure is clarified by the x-ray diffraction measurements.
