Description

Using synchrotron X-ray and pair distribution function analysis of powder neutron diffraction data, we show that the LTT phase of La2-xBaxCuO4 supports superconductivity at high (27 K) Tc's. We also show that the structural change at the LTO-LTT transition is different from that of the crystal structure models. The implications are discussed. ((orig.))
