Abstract
The decay of magnetization with time is recorded for a quench-melt-gro wth processed YBa2Cu3O7-x sample. The vortex-glass and collective pinn ing theories fit the data quite well over all time regimes with an exp onent, mu, value of O.78. The normalized logarithmic magnetic relaxati on rate, S, attains a plateau value of 0.05, considerably higher than a variety of samples which fall within a universal plateau curve.
