Abstract
In the strongly correlated 4f-electron compound CeRh2Sn 2 the ground state is governed by long-range magnetic ordering in the Ce-ion sublattice. At the same time, the electronic properties in CeRh2Sn2 display the consequences of a remarkable enhancement of the electron mass which indicates a strong electronic correlation between the 4f-electron responsible for magnetic ordering and the degenerate conduction electrons. The purpose of this work is to explore these effects when diluting the cooperative behaviour of the magnetic Ce+3 species in CeRh2Sn2 by means of the isotructural, nonmagnetic compound LaRh2Sn2. Moreover, the La compound becomes superconducting at low temperature and thus provides an additional dimension to studies of the stability of magnetism in this system.
