Abstract
The Mössbauer effect spectra of Pr2Fe17D3, which have been measured between 85 and 295 K, indicate the presence of a spin reorientation of the iron magnetic moments at 105±5 K. At this magnetic transition a large increase of ~50 kOe in the 6c iron magnetic hyperfine field and abrupt changes in all of the remaining hyperfine fields are observed. A study of the changes in the quadrupole shifts at the transition indicates that this spin reorientation takes place within the basal plane of this rhombohedral compound. As expected, the temperature dependence of the isomer shifts does not show any anomaly at the transition. The origin of this spin reorientation is attributed to competing effects between lattice expansion upon deuteration and lattice contraction upon cooling.
