Abstract: We investigate the continuous variation of electronic states from a Fermi liquid to a quantum spin liquid induced by chemical substitution in the organic dimer-Mott system of κ-[(BEDSeTTF)x(BEDT-TTF)1−x]2Cu[N(CN)2]Br. Electrical transport measurements reveal that the mixing… read more here.
