Title: Substitution in ce2tsi3 intermetallic compositions with t = (Cr, Mn, Fe, Co, or Ni) x (Pd or Au) 1-x. Technical report No. 30

Abstract

Alloys of composition Ce2(3d/T)Si3, with `3d` one of Cr, Mn, Fe, Co or Ni and `T` being Pd or Au, were separated and examined by powder x-ray diffraction. Select single phase compositions were further examined by magnetic susceptibility, by resistivity for the Pd and Co end-members and by specific heat for Ce2CoSi3. For compounds not containing cobalt, effective cerium moments consistent with trivalent cerium were observed. A re-examination of the AlB2 related structure of Ce2CoSi3 by single crystal methods revealed ordering of cobalt within the CoSi3 hexagonal layer. Magnetic susceptibility, resistance and specific heat measurements suggest valence fluctuation behavior of the cerium in Ce2CoSi3. A return to trivalent cerium magnetic behavior occurs on increasing palladium or gold substitution for cobalt.
