Superconductivity in Bi2Sr2Ca1-xCexCu2Oy

Abstract

Effect of Ce-ions substitution for Ca ions in the superconducting Bi2Sr2CaCu2Oy has been investigated. Up to the Ce concentration x=0.5, the powder x-ray diffraction exhibits a pattern similar to the non-substituted one. The resistivity measurement shows that Tc slightly increases first with the substitution and then tends to decrease above x=0.05. Further, the system undergoes the metal-insulator transition around x=0.32. The Hall coefficients stay positive and increase with the substitution. These behaviors resemble to those observed for Bi2Sr2Ca1-x(Y or Tm)xCu2Oy, provided that Bi2Sr2Ca1-x- CexCu2Oy should correspond to Bi2Sr2Ca1-2xox(Y or Tm)2xCu2Oy on account of the difference of the formal valences of Ce4+ and Y3+ or Tm3+.
