Description

The dc electrical conductivity of a series of Lasub(2 -x)Srsub(x)CuO4 compounds has been investigated. At room temperature the compounds exhibit a continuous change from the orthorombic to the tetragonal structure as x is increased from zero to x = 0.15. Superconductivity appears in the tetragonal phase. The resistivity maximum, preceeding the superconducting transition varies in correlation with the Sr concentration. Application of hydrostatic pressure supresses the resistivity maximum. (author)
