Abstract
We discuss studies of TmVO4, TmF2, TmF3 and TmSe utilizing the 8.4 keV Mössbauer resonance in 169Tm. The studies cover a temperature range from 0.050 K to 365 K and Mössbauer information is derived which pertains to the following phenomena : 1) the Jahn-Teller distortion in TmVO4 at 2.1 K ; 2) the removal of the ground state degeneracy in TmF2 in spite of cubic environment and the absence of magnetic order ; 3) the temperature dependence of the quadrupole interaction in TmF3, and 4) the mixed valence state character and magnetic ordering observed in TmSeKeywords
