The magnetic moments of some RAl/sub 2/ (R = rare earth element) cubic Laves phase compounds were measured at temperatures from 1.4 to 300 deg K. The measurements indicate that the spin moments of the rare earth ions are coupled ferromagnetically. The Curie points of the RAl/sub 2/ compounds are found to be uniformly higher than the corresponding Laves compounds, ROs/sub 2/, Rlr/sub 2/ and RRu/sub 2/. Solid solutions of some of the compounds were also investigated. For example, in the Gd/sub x/Pr/sub (1-x)/Al/sub 2/ compounds, the magnetic moments of the Gd ions are antiparallel to those of the Pr ions because J is antiparallel to S in the ground state of the Pr ion. Compensation points were observed in this system. (auth)
