摘要：

The results of low-temperature Mössbauer measurements on the dihydrides and dideuterides of Er and Ho are presented in the range 1.5-10 K. The magnetic ordering temperatures observed from the onset of magnetic hyperfine splitting are in agreement with the specific heat measurements. The saturation hyperfine magnetic field at 166Er in ErH2 and ErD 2 show the ground crystalline-field level to be Γ6, while it is difficult to decide between Γ6 or Γ7 as the ground state for the Er atom in HoH2 and HoD2. The measurements indicate the presence of short-range magnetic order in all the cases. Furthermore, the temperature range over which the short-range magnetic order is observed is intimately related to the stoichiometry of the hydrides or the deutrides.
