摘要：

High-field isotherms at low and high temperatures and other magnetic properties of R2Co17 (R=Pr, Nd, Sm, Gd, Th, Dy, Ho, and Er) measured on single crystals are analyzed on the basis of the single-ion model. The fitted crystalline electric-field parameter A20 for the Pr ion is several times smaller in absolute value than those for all the other rare-earth ions. The result is similar to that observed in the RCo5 series, and it is suggested that the Pr ion in Pr2Co17, as in PrCo5, is valence fluctuated.
