ABSTRACT
Substitution of Y for Ca in the high Tc superconductor system Bi4Sr3Ca3-xYxCu4O16+δ (0≤x≤1.5) is accompanied by an increase in oxygen concentration δ≊0.34+0.3x that is insufficient to compensate for the increase in counter-cation valence. Nevertheless, Tc≊86 K remains nearly constant in the interval 0≤x≤0.5; it drops smoothly to zero in the interval 0.5
