Abstract

Limiting ourselves to the weak-coupling model and neglecting the Pauli paramagnetism and the spin-orbit coupling, we determine the upper critical field of the axial (E1u) and the hybrid (E1g) state numerically. When the external field H is parallel to the symmetric axis (the c axis), the solution proposed by Luk’yanchuk and Mineev is analyzed. When H is perpendicular to the c axis, we find the exact solution for the axial state, while we construct approximate solutions for the hybrid state.
