Abstract
- The <f>E–J</f> characteristics were measured for a YBCO-coated conductor by using the four probe method and the relaxation method of DC magnetization. The result on the latter measurement at extremely low electric fields was theoretically analyzed based on the flux creep-flow model. From the result on <f>n</f>-value the flux lines in YBCO are considered to be in the glass state even at high fields. The apparent pinning potential <f>U0&ast;</f> estimated from the relaxation of DC magnetization is much larger than that of Bi-2223. The present theoretical analysis clarifies a much stronger flux pinning and a higher dimensionality of YBCO in comparison with Bi-2223. [Copyright &y& Elsevier]
