摘要：

The effect of Impurity scattering on upper critical fields in the axial state (P) and the hybrid state (D) is studied within weak coupling model. Unlike S-wave superconductor, impurity scattering suppresses both the transition-temperature T(c) and upper critical field H(c2)(T). However, when H(c2)(x,T)/H(c2)(x,o) is plotted against T/T(c)(x), the curves for different x(= 0.5669 (tau T(c0)-1) almost collapse into a single curve. This behavior should give another test of unconventional superconductors.
