While typical features associated with a transformation from the Kondo-lattice to single-ion Kondo effect are seen in the low temperature rho data of both the solid solutions, there are profound differences in their behavior at higher temperatures. In particular, Y is apparently more effective in enhancing the Kondo temperature. La2RhSi3 is found to be superconducting below 3 K.To be published in Solid State Physics (India) 2003Materials Sciencetext
