摘要：

Magnetic susceptibility (T) data from 84 to 300 K are reported for a Bi2Sr2CaCu2O8 single crystal. The (T) data with Hc exhibit negative curvature up to 150 K, attributed to superconducting-fluctuation diamagnetism, whereas those with Hc are independent of temperature above 90 K. From a theoretical fit to the data with Hc, the Ginzburg-Landau coherence length ab(0) is found to be 10.9. The room-temperature orbital and spin susceptibilities and their anisotropies are estimated and compared with those of YBa2Cu3O7. © 1990 The American Physical Society.
