摘要：
The relationship between the low-temperature orthorhombic-tetragonal (OT) phase transition in La2-xBaxCuO4 and the suppression of the superconducting state in samples with x = 0.125 has been investigated. Using high resolution synchrotron x-ray diffraction we show that the phase composition of a superconducting x = 0.15 sample varies with temperature identically to an x = 0.125 sample. This shows that the tetragonal structure does support bulk superconductivity in La2-xBaxCuO4 and the electronic transition which suppresses superconductivity at x = 0.125 is distinct from the OT structural transition.
