Abstract

Abstract We report the effects of Au substitution in the Heavy Fermion system Ce(Pt 1−x Au x )Si (0≤x≤0.10), invetigated by x-ray diffraction, electrical resistivity, and dc magnetic susceptibility measurements. CePtSi crystallizes in the LaPtSi-type tetragonal structure with 14 1 md space group and with lattice parameters a =0.4197 nm, and c =1.447 nm. The unit cell volume increases with increasing Au concentration, mainly due to an increase in the c lattice parameter. Electrical resistivity and dc magnetic susceptibility are presented for the temperature range 2 to 350K. We find the possibility of additional electronic mass enhancement in Ce(Pt 0.94 Au 0.06 )Si and a strongly compensated moment (1.3ω B ) for x≥0.08, which we attribute to Kondo compensation.
