La2-xSrxCuO4Lake TeleLimnologyMagnetismMeteoritePalynologychemical potentialWe have made photoemission studies of La 2 x Sr x CuO 4 (LSCO) and found the following: (1) suppression of the chemical potential ( μ ) shift for small x indicates a breakdown of the Fermi-liquid picture in the ...
The effect of partially substituting praseodymium for lanthanum in the superconducting materials La//2// minus //xSr//xCuO//4 has been investigated. Powder neutron diffraction work demonstrated that only minor structural changes occur; however, marked differences in electrical properties were found. Co...
