Nuclear spin lattice relaxation rates were measured in normal and supercond
ucting (sc) rhodium with nuclear polarizations up to p = 0.55. This was suf
ficient to influence the sc state of Rh, whose T, and B-c, are exceptionall
y low. Because B-c << B-loc and the short-range spin-spin interaction is un
changed, the nuclear spin entropy was fully sustained across the sc transit
ion. The relaxation in the sc state was slower at all temperatures without
the coherence enhancement close to T-c. Nonzero nuclear polarization strong
ly reduced the difference between the relaxation rates in the sc and normal
states.
