Abstract: | Zero field Mössbauer measurements have been carried out between 1.9 and 30 K and at room temperature on a -3 at% Fe sample. There is a quite well defined change of regime at about 19.5 K, well above the cusp temperature of this sample which was measured to be 16.4 K. In the temperature region below 19.5 K the spectra can best be described in terms of a static, inhomogeneously broadened field distribution, and at higher temperatures the spectra are compatible with relaxation broadening. Estimated relaxation rates in this regime are similar to those obtained by other techniques. |
