Abstract
The effect of heat treatments and quenching with no change in oxygen c ontent was studied for a polycrystalline sample of YBCO. Quenching the sample changes the properties drastically, as seen in the specific he at and the resistivity. This study shows that non-superconducting regi ons, some of which are not associated with Cu2+ moments, can be create d in YBCO by heat treatment alone.
