Abstract

A rich variety of behaviours have been found studying the physical properties of Ce-lattice systems tuned around their critical regions, particularly in the few phase boundaries traced along more than a decade of temperature. The phase diagram of two Ce-systems: the antiferromagnetic CeIn3-xSnx and ferromagnetic CePd1-xRhx are analyzed covering the 10K > T > 0.02K range of temperature. Their respective magnetic phase diagrams are described as an interplay between different components determined after analyzing their thermodynamic properties. In the former compound, signs for the formation of a new phase are observed at very low temperature, whereas in the latter a field induced contribution is detected behind the critical point..
