- W1971466277 abstract "Abstract Metallic - oxygen compounds in pseudo ternary systems La Cu M O with M=Sr, Pb have been prepared by high temperature solid state reaction under different conditions. The susceptibility measurements on La 1.85 Sr 0.15 CuO 4 show the onset of superconductivity at T c =41K and Hc 1 of 450 Oe. at 4.1K. Substitution of Sr by Pb destroys this superconductivity. For the Eu doped sample T c =17K, while La 1.6 Y 0.25 Sr 0.15 CuO 4 does not exhibit superconductivity down to 4.1K. The tetragonal lattice of La Sr Cu O shrinks in the a axis and expands in the c axis compared to R 2 CuO 4 R=Pr Gd. The role of this distortion in the metallic conductivity and superconductivity mechanism is discussed." @default.
