Abstract
The Kondo effect in a -wave superconductor is studied by applying the Wilson's numerical renormalization group method. In this type of superconductor with a full energy gap like a s-wave one, the ground state is always a spin doublet, while a local spin is shrunk by the Kondo effect. The calculated magnetic susceptibility indicates that the spin of the ground state is generated by the orbital effect of the -wave Cooper pairs. The effect of spin polarization of the triplet superconductor is also discussed.
