Crystal structure of HgBa2Ca2Cu3O8+ delta at high pressure (to 8.5 GPa) determined by powder neutron diffraction.

Abstract:

The crystal structure of the high-temperature superconductor HgBa2Ca2Cu3O8+δ has been determined from powder neutron-diffraction experiments up to pressures of 8.5 GPa. Complete structural refinements were carried out on the experimental data taken at (approximate) pressures of <0.5, 3.5, 6.0, and 8.5 GPa. One of the most significant features to emerge from this study is the extreme sensitivity of the apical Cu-O bond to applied pressure. Between our ambient and high-pressure measurements ...
