The magnetic transition temperatures for SmRh/sub 4/B/sub 4/ and ErRh/sub 4/B/sub 4/ are calculated for the Ruderman-Kittel-Kasuya-Yosida interaction as a function of Fermi wave-vector k/sub f/ and electron mean free path l. The results are consistent with the experimental l dependence and the antiferromagnetism (ferromagnetism) in SmRh/sub 4/B/sub 4/ (ErRh/sub 4/B/sub 4/) for values of k/sub f/ approximately equal to 1.84 A/sup -1/ (1.95 A/sup -1/). This result cannot, however, assess whether or not direct dipole-dipole interactions are significant for T/sub M/ in ErRh/sub 4/B/sub 4/.
