| dc.description | High-field magnetisation measurements up to 38 T have been performed on single-crystalline Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+ delta </sub> in order to investigate the irreversible behaviour associated with the flux line dynamics. It was found that the irreversible magnetisation vanishes asymptotically at high fields well below B<sub>c2</sub>. As temperature is increased, above approximately 40 K, the magnetisation essentially become reversible. Critical currents J<sub>c</sub> and volume pinning forces F<sub>p</sub> were calculated and compared with the results of YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7- delta </sub>. The irreversibility line deduced from the present measurements as well as from other techniques is discussed in terms of a possible boundary, above which superconducting phase fluctuations play a dominant role for the dissipation. |
