Abstract
The anisotropy of the superconducting state of high quality single crystals of was determined, using torque magnetometry with two different methods. The anisotropy of the upper critical field was found to be temperature dependent, decreasing from at 15 K to 2.8 at 35 K. Reversible torque data near reveal a field dependent anisotropy, increasing nearly linearly from in zero field to 3.7 in 10 kOe. The unusual temperature dependence is a true bulk property and can be explained by nonlocal effects of anisotropic pairing and/or the dependence of the effective mass tensor.
