Single-ion Kondo behavior of a novel Kondo lattice, CeNi9Si4
Abstract
The compound, CeNi9Si4 has been recently reported to be an unusual Kondo lattice with a large Ce-Ce separation, with a breakdown of Kadowaki-Woods relationship governing low temperature electrical resistivity and heat-capacity. Here we report the results of magnetic susceptibility, heat-capacity and electrical resistivity of the solid solution, Ce(1-x)La(x)Ni9Si4 to understand the Kondo behavior of this compound. The results establish that the observed properties of Ce in this compound are single-ionic in character.
