| Abstract: | The hexagonal compound TmNi5 was investigated by means of 169Tm Mössbauer spectroscopy in the temperature range 4–350 K. Above Tc=4.5 K the magnetic hyperfine interactions were found to be governed by paramagnetic relaxation. This behaviour was interpreted in terms of a stochastic spin-down model. The spin lattice relaxation time was found to follow an exponential temperature dependence. |
