摘要：

The composition of the tetragonal cuprates REBa2Cu3O7-delta (RE = Y and Ho) was investigated by X-ray and neutron single crystal diffraction analysis and by electron microprobe analysis. The combination of the neutron diffraction analysis and the electron microprobe analysis on the same crystal samples yielded the compositions YBa2Cu2.874(8)Al0.10(1)O6.31(2) and HoBa2Cu2.890(8)Al0.11(1)O6.53(2), respectively. The single crystals were grown in an Al2O3 crucible from a BaO-CuO flux, and the Al content in the crystals comes from the crucibles used.
