Abstract

We have carried out the flux flow experiments for two single crystal samples with the residual resistivity ratio RRR = 240 and 12 which differ highly in quality. The peak structure, which is observed in the vicinity of Hc2, is dominant for the RRR = 12 sample, while it is slightly observed for the RRR = 240 sample. The flux flow, however, starts at a low field for the RRR = 12 sample, compared to that for the RRR = 240 sample. It means that a pinning force for the RRR = 12 sample is smaller than that for the RRR = 240 sample. These characteristic features might be closely related to layered defects and Ru-vacancies which exist heavily in the RRR = 12 sample.
