摘要：
The effect of heat treatments and quenching with no change in oxygen content was studied for a polycrystalline sample of YBCO. Quenching the sample changes the properties drastically, as seen in the specific heat and the resistivity. This study shows that non-superconducting regions, some of which are not associated with Cu2+ moments, can be created in YBCO by heat treatment alone.
