Pulsed and cw-NMR measurements of /sup 11/B have been used to study the spin dynamics of magnetic rare earth ions in (Y/sub 1-x/RE/sub x/)Rh/sub 4/B/sub 4/. We find the nuclear spin-lattice relaxation rate of /sup 11/B induced by RE = Tb, Dy and Ho moments to be exponential in -..delta../T in the normal state, where ..delta.. is the crystal field splitting of the first excited state. Anomalous temperature dependencies of the transverse relaxation time T/sub 2/, Knight shift and NMR line width in (Y/sub 1-x/Dy/sub x/) Rh/sub 4/B/sub 4/ are obtained in the temperature region where T/sub 1/ changes drastically. The results are discussed in terms of a model of the crystalline electric fields, in which thermal activation across ..delta.. must take place for the ..delta..m/sub J/ = +-1 transition to occur in highly anisotropic paramagnetic moments in the ternary superconductors.
