Abstract

The effects of lanthanide rare earth (RE) substitution into two layer bismuth superconductors are studied. Quenching the RE substituted superconductors, Bi_1.55Pb_0.45Sr₂RE_0.2Ca_0.8Cu₂O_z, is used to lower the hole concentration to the levels where above 90 K superconductivity can be achieved. Lead substitution is used to facilitate the growth of single phase specimens. Variation in the values of T_c for the various RE substituted superconductors is seen to be governed mainly by the value of the hole concentration in each of the superconductors.
