abstract = "The anisotropy of the upper critical field slopes and resistivity has been measured in sinter-forged YBa2Cu3O7-σ. An analysis based on the anisotropic Ginzburg-Landau theory, combined with a Gaussian fit to the measured angular distribution function of the crystallites was carried out. The fundamental quantities derived are consistent with the single crystal results, implying that this method is useful in determining the anisotropic properties (or in deducing the degree of the preferential orientation) in similar anisotropic compacts.",

The results can be understood in the framework of the anisotropic GL theory with an experimentally determined Gaussian angular distribution for the crystallites. For other similar materials, where single crystals are not available, the method proposed here may be applied to estimate the anisotropy of the coherence length. Alternatively if this anisotropy is known, the measured upper critical field anisotropy on a textured compact may be used to characterize the degree of orientation of its crystallltes (i.e., the parameter 9o).
