摘要：

New magnetic torque measurements on a high-quality Bi2Sr2CaCu2Ox single crystal show that only a lower bound for the anisotropy parameter gamma > 150 can be given. For misorientations of the field H from the (a, b) plane larger than 0.5-degrees, the results can be rescaled to magnetization M vs H. The behavior of M can be consistently described by a recent theory of Bulaevskii, Ledvij, and Kogan.
