✦ Synopsis

The angular dependence of the critical current density (J c ðyÞÞ and the vortex glass transition temperature (T g ðyÞÞ in La 1:87 Y 0:13 CuO 4 were measured at different fields and temperatures. Both J c ðyÞ and T g ðyÞ showed a strong angular variation, which is typical for anisotropic superconductors. The angular variation could be described by using the anisotropic three-dimensional Ginzburg-Landau theory. From our analysis, we were able to estimate the anisotropy ratio.
