Abstract
We have investigated the cubic Laves-phase compounds (Ce1-cGdc)Rh2 across the entire concentration range by means of magnetic measurements and lattice-parameter studies. The magnetic data show that only those cerium atoms having at least three nearest-neighbor gadolinium atoms are magnetic and in the ordered state they couple antiparallel to the gadolinium sublattice. With use of the Ruderman-Kittel-Kasuya-Yosida model and the lattice-parameter data, a value of 0.58 eV is obtained for the effective exchange integral. The x-ray data do not show the change of valency for cerium across the series.
