Phases of the type La 2 xyR xSr yCuO 4 z, where R is Pr, Nd, Sm, Eu, or Gd, have been prepared for various values of x and y. All phases prepared had the La 2CuO 4 structure. The general trend for fixed y is that T c decreases as the four coplanar Cu O distances ...
Electronic specific heat C e1 at T≦10 K was studied on La 2x Sr x Sr x Cu 1y Zn y O 4 below and above the critical Zn-content y c at which the superconductivity disappears. The specific heat C e1 of non-doped superconducting samples exhibits a T 2 -dependence, peculiar to a d...
