Abstract

We calculate the temperature T and angular (θ, φ) dependencies of the upper critical induction Bc2(θ, φ, T) for parallel-spin superconductors with an axially symmetric p-wave pairing interaction pinned to the lattice and a dominant ellipsoidal Fermi surface (FS). For all FS anisotropies, the chiral Scharnberg-Klemm (SK) state Bc2(θ, φ, T) exceeds that of the chiral Anderson-Brinkman-Morel (ABM) state and exhibits a kink at θ = θ*(T, φ), indicative of a first-order transition from its chiral, nodal-direction behavior to its non-chiral, antinodal-direction behavior. Applicabilities to Sr2RuO4, UCoGe and the candidate topological superconductor CuxBi2Se3 are discussed. © 2014 IOP Publishing Ltd.
