Abstract

Structural, thermal, magnetic, transport, and Ce L3-edge spectroscopic measurements on the Ce(MnxCr1-x)2Si2 series are presented. These results all indicate that Cr substitution drives this system from a mixed-valent Ce state at x=1.0 to a Kondo or heavy-fermion state with increasing x. The reflection of the Ce valence-state variation (from L3 measurements) in the electronic specific heat coefficient and lattice parameters is discussed. The magnetic and transport measurements indicate that the Ce spin-flip scattering processes (i.e., the Kondo effect) apparently thrive within the Mn-moment antiferromagnetically ordered phase of these compounds.
