Abstract
Substitution of bismuth by cadmium was investigated in the compounds B i2-xCdxSr2(Ln0.82Ce0.18)2Cu2O10+delta (Ln = Gd, Eu, Dy and Ho) and the effect on superconducting properties was studied. Bi2Sr2 (LnCe)2Cu2O1 0+delta treated under high oxygen pressure up to 50 atm displayed semi conducting behavior instead of superconductivity. Superconductivity oc curs in Cd-substituted compounds with a maximum T(c) of 36 K for the G d derivative under the same treatment conditions.
