Abstract
High-resolution neutron powder diffraction experiments on the superconducting compound La1.85Ba0.15CuO4 have revealed the presence of a tetragonal-to-orthorhombic phase transition at 180 K, together with subtle, anomalous structural instabilities at lower temperatures. These experiments demonstrate a correlation between the structural anomalies and changes in the electrical resistivity.
