Abstract We have synthesized the single phase samples of Cu x C 0.1 Ba 2 Ca 3 Cu 4 O z (x=0.2∼0.9). Transport and magnetic measurements and iodometric titration analysis were carried out for these materials. From these results we discuss the correlation between T c , the Hall number, copper valence and oxygen content. The effect of the substituted M ions on T c in (CuC, M)-l234 (M=Ni,Zn,Al,TI,Mg) is also discussed. We propose a unique selective carrier-doping mechanism in (Cu,C)- and (CuC,Mg)-1234 systems.
