Metals on the border of magnetism have attracted great attention in recent times, as a number of them exhibit a superconducting phase at low temperatures in the vicinity of the critical pressure at which the magnetic transition temperature is suppressed to zero. We present a brief overview and comparison of the body centered tetragonal compounds CePd sub 2 Si sub 2 and CeNi sub 2 Ge sub 2 , and the simple cubic CeIn sub 3 . In spite of the differences in structure and the detailed behaviour in the unconventional normal state near the critical pressure, these compounds share the existence of superconductivity at the border of antiferromagnetic order, and therefore are prime candidates for the study of a possible magnetic pairing mechanism. In this paper, we will solely present a comparison of the normal state properties of these materials.
