在高质量bi2sr2cacu2ox单晶上的新磁转矩测量表明，各向异性参数γ>150只能给出一个下界。对于（a, b）平面的场H的取向偏差大于0.5°，结果可以重新调整为磁化强度M vs H。M的行为可以用Bulaevskii， Ledvij和Kogan最近的理论一致地描述
New magnetic torque measurements on a high-quality Bi 2 Sr 2 CaCu 2 O x single crystal show that only a lower bound for the anisotropy parameter γ>150 can be given. For misorientations of the field H from the (a, b) plane larger than 0.5 o , 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
