We found a normal-state reentrant behavior in zero held near the critical t
emperature of a Bi2212 crystal when we applied current along c-axis directi
on and measured the ab plane voltage. A similar phenomenon is observed in a
Zn substituted Bi2212 crystal. The new phenomenon may be due to destroying
of the Cooper pairs in the ab plane by the injected normal electrons. (C)
