The superconductivity in samples nominally described as Bi2(Sr1-xLnx)2Cu1+nOy (Ln: lanthanide elements and yttrium: n=0 and 1) was investigated. The effect of an increasing TC compared with that of Bi2Sr2CuOy was observed for Ln=La, Pr and Nd. The highest end-point of the transition temperature of Bi2(Sr1-xNdx)2CuOy was 20.4 K with x=0.25. Compounds described as Bi2(Sr0.95Ln0.05)2CuOy (Ln=Pr and Nd) had an onset TC of about 60 K, and small but definite Meissner effects were also observed.
