Abstract

The magnetic-field-induced fluctuation effect in a highly textured Bi/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub 10/ tape is studied, based on magnetization measurements. Extremely large induced excess diamagnetism in high fields was observed at temperatures down to 75 K. In weak fields, fluctuation significantly reduced the diamagnetism of this system just below T/sub c/. The role this large extended fluctuation effect plays in the application of the Bi-based superconductor family is discussed.<>
