Yb-based Kondo lattice systems (YbAgCu/sub 4/, YbCu/sub 2/Si/sub 2/, YbRh/sub 2/Si/sub 2/) represent an interesting class of materials in which it is possible to study systematically the development of heavy electron behavior through the application of pressure. Certainly, additional experiments are required to determine to what extent Yb compounds are mirror images of their Ce counterparts. Finally, pressure reveals the presence of competing interactions for which a simple model exists that qualitatively accounts for the pressure response observed in a large number of Ce, U and Yb-based Kondo lattice systems.
