Calculating the distribution of transferred hyperfine fields at the Sn site in tetragonal CeScSi-type RMgSn compounds
Résumé
We present a simple model based on an isotropic transferred hyperfine field to calculate the transferred hyperfine field distribution at the Sn site of the antiferromagnetic CeScSi-type RMgSn compounds. The calculations correctly reproduce the main features observed in NdMgSn, TbMgSn, DyMgSn, HoMgSn, and ErMgSn. The transferred hyperfine field distributions are remarkably sensitive to the complex magnetic structures in the RMgSn compounds, and can be used to discriminate between competing magnetic structure models.
