The electrical resistivity of the intermediate-valent ytterbium compound YbAu2ln has been investigated under high-pressure conditions (Alami-Yadri et al., 1998) up to 8 GPa. The Kondo temperature decreases with increasing pressure, while the residual electrical resistiv-... 

Spedding and Daane (1961) have reported that a 50% alloy of ytterbium in cerium was observed to contain two immiscible liquids. An X-ray study of these phases indicated a solubility of 1 at% Ce in Yb and 3 at% Yb in Ce. King (1969) studied electrical resistance of ytterbium-rich alloys of the cerium-ytterbium phase diagram and observed that an addition of 10 at% cerium moved the resistance peak in pure ytterbium from 3.937 to 5.27 GPa at room temperature. 

King (1969) measured electrical resistance as a function of pressure on alloys in the Yb-rich portion of the Eu-Yb system. Alloys in this 5 tem were difficult to prepare because of the volatility of europium and so it was necessary to confirm the compositions on the basis of lattice spacing data, none of which were presented in King s paper. Additions of europium lowered the fcc()8)5 bcc(y) transformation that occurred at 3.94 GPa for pure ytterbium to 3.1 GPa for the 70at% Yb alloy.
