Abstract :
The effects of waiting time on reptation measurements have been calculated. These effects are found to account for the observed change in magnetization with field cycles even if the waiting time prior to the measurement is extended to the order of hours. Thus for reptation measurements the effects of time dependence will not saturate by extending the waiting time. Both the appropriate calculation of these effects and supporting experimental results are presented
