The bulk magnetic properties of tetragonal, oxygen-depleted, polycrystalline samples of sintered R/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7/..sqrt../sub x/ compounds with x = 0.95 have been investigated. Materials containing the rare-earth (RE) ions Gd, Dy, and Ho were studied. In each case, the magnetic susceptibility chi was described by a Curie-Weiss (CW) dependence with effective moments that were very nearly equal to the free-ion values--behavior that is very similar to the superconducting counterparts of these materials where the oxygen has not been depleted. The field dependence of the magnetization M(H,T) was found to be substantially modified by crystalline electric field effects and by the influence of Re-Re interactions.
