An adiabatic--field-cycle method for /sup 11/B nuclear magnetic relaxation has been used to study the spin dynamics of rare-earth ions in dilute (Y/sub 1-x/R/sub x/)Rh/sub 4/B/sub 4/. Longitudinal dipolar fluctuations of rare-earth moments are found to be the main source for the spin-lattice relaxation time of /sup 11/B. The variation of T/sub 1/ in the superconducting state is attributed to the reduction of the electronic spin-relaxation time tau/sub m/, which is mainly determined by the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction mediated by the conduction electrons. The remarkable reduction of the RKKY coupling below T/sub c/ is discussed in connection with the reduction of the conduction-electron spin susceptibility chi(q).
