    (University of the Western Cape, 2008) Tshabalala, Kamohelo George; Tchokonté, Moїse Bertin Tchoula; Du Plessis, Paul De V.
    The present study investigates the strength of the hybridization by substituting Ce atom in Kondo lattice CeIn3 with Gd, Tb, and Dy and by changing the chemical environment around the Ce atom in substituting Pt with Ni in CePtSi2. This thesis covers four chapters outline as follows: Chapter 1 introduces the theoretical background in rare earths elements, and an overview of the physics of heavy-fermion and Kondo systems. Chapter 2 presents the experimental details used in this thesis. Chapter 3 report the effect of substituting Ce with moment bearing rare-earth elements RE = Gd, Tb and Dy in CeIn3, through x-ray diffraction (XRD) and electrical resistivity measurements
