Abstract

We have mapped the temperature and composition dependence of the tetragonal-orthorhombic phase-transition temperature Td in the high-temperature superconductor La2-xSrxCuO4- using high-resolution powder x-ray diffraction and measurements of the thermal expansion. The maximum volume fraction of ideal diamagnetism occurs in the composition range where Td is approaching the superconducting transition. In the composition range x>0.20 where no orthorhombic distortion is observed above 12 K, no bulk superconductivity is observed in La2-xSrxCuO4-.
