Abstract In this thesis, a study is made of hyperfine interactions in the intermetallic compounds Rsub(x)Fesub(y) (R = rare earth, Y or Th) by using the Moessbauer effect in the exp 57 Fe nucleus. The hyperfine interactions in two series of Rsub(x)Fesub(y) compounds, for which Ysub(x)Fesub(y) and Ersub(x)Fesub(y) were chosen, are studied. Thus a comparison can be made between the magnetic properties of compounds with diamagnetic yttrium and ferromagnetic erbium, respectively. In addition, the magnetic anisotropy of these compounds Ysub(x)Fesub(y) and Ersub(x)Fesub(y) has been investigated. The major part of this thesis concerns a study of the R sub 2 Fe sub 17 intermetallic compounds. Since Co or Ni substitution for Fe in R sub 2 Fe sub 17 compounds results in a fast increase of the Curie temperature, some pseudobinary R sub 2 Fesub(17-x)Msub(x) compounds with R = Tm and Er and M = Co and Ni, have been investigated. ThFe sub 5 has been studied, since it is the only known existing RFe sub 5 compound with a crystal structure which is closely related to that of Th sub 2 Fe sub 17 . (Atomindex citation 08:304270)
