Figure 1

Schematic of the pressure-temperature phase diagrams and pressure dependence of 4f electron numbers for Yb and Ce systems, where T N, T K, and AF are Néel temperature, Kondo temperature, and antiferromagnetic ordered sate, respectively3, 5. In the Yb system, two quantum critical points (QCPs) are possibly observed. An image of the crystal structure of cubic YbCu5 is also shown.
