Abstract

On small single crystals of 2H NbSe 2 we have measured the temperature and angular dependence ofH c2 as well as the temperature dependence ofH c1 close toT c. Using an effective mass approach to the Ginzburg-Landau equations we have analyzed our data in terms of an anisotropic κ and obtained values for the coherence distances and penetration depths parallel and perpendicular to the layers. The connection between these parameters and normal-state properties is discussed and shown to be more complex than in the isotropic case.
