Abstract
The system Ce-Sn has been reinvestigated in the temperature range from 400 to 800 °C using X-ray powder diffraction techniques. From a characterization of its crystal structures the existence of nine binary compounds has been confirmed.
Magnetic investigation of the binary cerium stannides in the temperature range from 4.2 to 600 K revealed a systematic tendency for ferromagnetic ordering of the ceriumrich compounds up to a ratio Ce:Sn ≈ 1, followed by antiferromagnetism up to a ratio of Ce:Sn ≈ 0.4, towards interconfigurational fluctuation in the compound richest in tin, CeSn3. Candidates for heavy fermion behaviour found in the transition regions, besides CeSn3, are α-Ce5Sn3 and Ce11Sn10.
