Abstract

We present our study on the magnetic field induced fluctuation effect in a highly textured Bi2Sr2Ca2Cu3O,0 tape, based on the magnetization measurement. Extremely large induced excess diamagnetism in high fields was observed at temperatures down to 75 K. In weak fields, fluctuation significantly reduces the diamagnetism of this system just below Tc. The role of this large extended fluctuation effect played in the application of Bi-based superconductor family is discussed.
