Abstract
The reversible magnetization for H∥ab has been studied for grain-aligned (Formula presented)(Formula presented)(Formula presented) in order to determine whether the Hao-Clem theory can properly describe the vortex state in this orientation, as well as the orientation for H∥c. Between temperatures of 70 and 76 K, the magnetization is reversible to better than 2% and the results scale very well to the universal Hao-Clem curve even though the supercurrents have a highly noncircular path as they circulate around a vortex parallel to the ab plane. The thermodynamic critical field is the same for H∥ab as for H∥c, as expected, and the Ginzburg-Landau parameter (Formula presented)=380 compared to (Formula presented)=70 is consistent with an anisotropy value γ=5.8±0.4.
