Abstract
The thermal expansion and magnetostriction of single crystals of normal and ferromagnetic dense Kondo systems CeSi1.86 and CeSi1.70 are measured. The results show very characteristic behavior. The strain-dependent Kondo effect supports the Γ7-like ground doublet conjectured previously based on the analysis of the magnetic susceptibility data. It is shown that the result is similar to that in the usual nearly weak ferromagnetic system.
