Magnetization-temperature data are presented for the hydrides DyH_1.97 to DyH_2.97, ErH_1.96 to ErH_3.02, and TmH _1.99 to TmH _2.96 and for the three parent metals. Of the 15 hydrides examined only the Dy hydrides exhibited magnetic ordering. These hydrides showed a Neel point at nearly the same temperature as that found earlier for HoH₂, 8 deg K. The susceptibilities followed the Curie-Weiss law over most of the paramagnetic region with an effective moment nearly that of the free tripositive ion. Deviations from the Curie- Weiss law noted at low temperatures are attributed to crystal-field effects. The absence of magnetic ordering in the saturated hydrides is ascribed to the fact that these hydrides lack conduction electrons, which are essential for the magnetic coupling.
