Based on possible existence of technique effect and scattered distribution in positron results, a special investigation was made for YBa2Cu3O7 � d systems in this paper. The dependence of preparation techniques and the structural characteristics on the sintering temperature and time are also given by positron lifetime, XRD and SEM experiments. The results show that the positron lifetime parameters and the microstructure show a significant dependence on sintering temperature and time. It is… CONTINUE READING
