โฆ Synopsis
We investigated the effect of quenching on the critical temperature 7, of sintered Bi&,CuO, (2201-phase ). The mtdpoint I, of the 2201-phase was raised from 6 to I7 K by quenching. The resistive onset temperature of the quenched sample reached 60 K. The r, behavior was similar to that of Bt2SrzCaCu,0, (22 12 ).
