摘要
We study the anisotropy of the upper critical field (H-c2) while changing the direction of the applied magnetic field for various order parameters considered in a layered Superconductor Sr2RuO4. The Pauli paramagnetic effect can play an important role in identifying the spin structure of the underlying order parameter. The recent H-c2 measurement by Kittaka et al. can be explained either by spin-triplet order parameters having a d-vector in the basal plane or by spin-singlet ones, such as s- and d-wave gaps.
