Abstract: | The effects of superconducting fluctuations are investigated in a small metallic particle with spin-orbit scattering at the surface and impurity sites. The spin susceptibility and the nuclear spin relaxation time are calculated, using the Green's function method developed in a preceding paper. At low temperatures the spin susceptibility takes a value closer to that of Pauli paramagnetism than in the case without spin-orbit scattering. The effect of the Zeeman energy on the relaxation time is reduced. It decreases the enhancement of the relaxation time. These results are in good agreement with NMR experiments for tin particles. |
