/sup 121/Sb Moessbauer investigation of the rare earth antimonides

Journal Article · · J. Solid State Chem.; (United States)
/sup 121/Sb Moessbauer spectra have been obtained for the series R Sb (R = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Yb) at 78/sup 0/K and for a selection of the compounds at 5.5/sup 0/K. At 78/sup 0/K all the spectra show a single line. The isomer shifts are close to that of InSb and show a linear increase with increasing atomic number of the rare earth ion. Many of the rare earth antimonides exhibit a variety of magnetic and structural phase transitions at a sufficiently low temperature. Spectra obtained at 5.5/sup 0/K are interpreted in terms of these phase transitions.
