Thermal, electrical and magnetic properties of the ferromagnetic dense Kondo system CeSix

Article abstract of DOI:10.1143/JPSJ.57.1384

Single crystals of the ferromagnetic dense Kondo system CeSi_x were grown, and the specific heat, the electrical resistivity and the magnetic susceptibility were measured. Electrical resistivity measurements clearly show the typical Kondo behavior, which unambiguously tells that CeSi_x is a ferromagnetic dense Kondo system. The appreciable anisotropy of the magnetic susceptibility is analyzed with the crystalline field effect and a conjecture is made that the ground doublet is a Γ₇-like doublet.
