Abstract

The effect of Pb and/or Y doping on the hole concentration nh of Bi2-xPbxSr2Ca1-yYyCu 2O8+d was studied by means of optical absorption. Tc and magnetic response were examined in terms of fundamental and harmonic susceptibilities. The sample of x= 0, y = 0.2 shows the highest Tc. Further substitution of Y decreases both Tc and nh. Pb substitution introduces holes only for the case of poor nh samples. The pinning force density is enhanced with nh.
