Abstrakt: Hexagonal crystals of rare earth trifluoromethanesulfonate nonahydrates R(CF3SO3)3·9H2O, RTFMS are similar in structure to the rare earth ethylsulfate nonahydrates RES. ?||and ??measured between 0.06 and 20K show RTFMS salts with R = Tb, Dy and Ho to be dipolar ferromagnets ordering at 0.24K, 0.111K and 0.224K, respectively, as do the corresponding RES compounds. Like CeES, CeTFMS remains paramagnetic but their Ce3+level splittings are different. PrTFMS exhibits antiferromagnetic long-range order below TN?0.31K while PrES shows only short- range one dimensional order. Measurements of Cpfor TbTFMS and PrTFMS confirm their phase transitions.
