Magnetic-susceptibility anisotropy of single-crystal Bi sub 2 Sr sub 2 CaCu sub 2 O sub 8

Magnetic susceptibility {chi}({ital T}) data from 84 to 300 K are reported for a Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} single crystal. The {chi}({ital T}) data with {bold H}{parallel}{bold c} exhibit negative curvature up to {approx equal}150 K, attributed to superconducting-fluctuation diamagnetism, whereas those with {bold H}{perpendicular}{bold c} are independent of temperature above 90 K. From a theoretical fit to the data with {bold H}{parallel}{bold c}, the Ginzburg-Landau coherence length {xi}{sub {ital a}{ital b}}(0) is found to be 10.9 A. The room-temperature orbital and spin susceptibilities and their anisotropies are estimated and compared with those of YBa{sub 2}Cu{sub 3}O{sub 7}.
