摘要：

CeRhSi2 and CeIrSi2 crystallize in the orthorhombic CeNiSi2-type structure. Magnetic susceptibility and electrical resistivity measurements reveal that cerium in each of these compounds is in an intermediate valence state, but also that the spin fluctuation temperature is much higher for CeIrSi2 than that observed for CeRhSi2. The magnetic behavior of the ternary silicides such as CeM2Si2, Ce2M3Si5, CeMSi3, and CeMSi2 with M = Rh or Ir depends on the average distance Ce-M which determine the strength of the 4f(Ce)-4d or -5d(M) hybridization. © 1993 Academic Press, Inc.
