Abstract
We have studied the dynamics of a melt-cast Bi-2212 sample, using data from the out-of-phase component of the ac susceptibility. The dynamic Freezing temperatures T-f(f) were scaled using conventional critical slowing down re lations. The results yield evidence of a chiral-glass phase transition, whi ch is suggested to lie in the universality class of the 3D Ising spin glass .
