Structural effects of hydrostatic pressure in Sr1-xMxCuO2 (M=La,Ca) and Sr4Cu6O10.
Pressure effects on the tetragonal infinite-layer structure were studied in superconducting Sr0.9La0.1CuO2 (electron-doped) and Sr0.7Ca0.3CuO2 (hole-doped) samples, and in an insulating nonsuperconducting Sr0.14Ca0.86CuO2 sample, using time-of-flight neutron powder diffraction.

| description | Pressure effects on the tetragonal infinite-layer structure were studied in superconducting Sr0.9La0.1CuO2 (electron-doped) and Sr0.7Ca0.3CuO2 (hole-doped) samples, and in an insulating nonsuperconducting Sr0.14Ca0.86CuO2 sample, using time-of-flight neutron powder diffraction. Neutron-diffraction measurements, with the sample at room temperature, were performed at several hydrostatic pressures up to 0.6 GPa on each of the three samples, using a helium-gas pressure cell. The measured compressibilities, which are similar for the three samples, show a large anisotropy, and are in a good agreement with first-principles calculations performed for undoped Sr0.7Ca0.3CuO2. Atomic size effects of the A atom in ACuO2 on the crystal lattice are discussed and are compared with the pressure effects. A relation is found between the in-plane compressibilities among n-layer (n=1,2,3..., structures of high-Tc superconductors. © 1994 The American Physical Society. |
