โฆ Synopsis
Generalizing an early theory of thermal conductivity of the vortex state in clean type II superconductors for unconventional superconductors, we have studied the anisotropy of thermal conductivity in the vicinity of B = He2 (T). The result is compared with recent experimental data on a single crystal of UPt 3. Among the superconducting wavefunctions belonging to D 6 symmetry and l ~< 3, both the axial (P-wave) and the hybrid (D-wave) states describe qualitatively the observed anisotropy.
