Sn2+ transferred hyperfine fields in the europium monochalcogenides doped with tin monochalcogenides

EuS, EuSe, and EuTe (but not EuO) are found to form solid solutions with the corresponding tin monochalcogenides. Transferred hyperfine fields (approximately 50 kOe) observed at the tin nuclei in dilute solid solutions using Moessbauer spectroscopy are shown to be supertransferred from the 2nd Eu neighbors. Experiments are indicated in which the Sn2+ fields can be utilized for testing zero-point spin deviation predictions and the theory of the Heisenberg non-magnetic impurity problem. (author)
