Pressure dependence of the structure of La-Sr-Cu-O
A high-resolution neutron powder diffraction study has been carried out to study the effect of pressure on the structure of the oxide superconductor La 1.85Sr 0.15CuO 4 in its room-temperature tetragonal phase. The refined atomic coordinates indicate an anomalous behaviour of the bond linking the co...
