Abstract

UPd₂Al₃ and URu₂Si₂ are considered to be non-s-wave superconductors with an anisotropic energy gap from the NMR and specific heat measurements. We have succeeded in observing clearly the dHvA oscillation in both the normal and superconducting mixed states. The cyclotron mass is found to be reduced and the Dingle temperature increases in the mixed state. An anisotropic energy gap with a line node for UPd₂Al₃ and URu₂Si₂ was discussed from the angular dependence of the dHvA amplitude in the mixed state.
