Non-stoichiometric YBCO was newly prepared by reduction of fully oxydized samples utilizing high purity inert gases at lower temperatures. The physical measurements such as electric resistivity, complex susceptibility, electron diffraction and nuclear quadrupole resonance were performed on thus prepared samples. A schematic phase diagram on non-stoichiometric YBCO dedused from these results has been proposed.
