摘要：

The intermetallic compounds YbPt3 and Yb3Pt 5, which present magnetic ordering below 0.25 K and 0.95 K respectively, have been investigated by 170Yb Mossbauer spectroscopy at very low temperatures. In YbPt3, the electronic ground Kramers doublet of Yb3+ has been determined, as well as its exchange splitting and spin-spin relaxation rate; the lowest Yb3+ crystal field excitation has been estimated. The surprising finding that the crystal electric field has strong axial character in YbPt3, instead of the expected cubic symmetry, is discussed.
