Magnetic behavior of CeFe/sub 2/: Effects of Ru, Rh, and Pd substitutions
Results are presented for the effects of substitution of Ru, Rh, and Pd for Fe in CeFe/sub 2/. For Rh and Pd the Curie temperature is lowered for up to 10% substitution without change in magnetic character. Ru substitutions produce (for 4% to 8%) the low-temperature loss of ferromagnetism observed for around 10% Co. At larger Ru substitutions no ferromagnetic regime is found but resistivity, susceptibility, and magnetization results suggest the presence of magnetic freezing which has some antiferromagnetic and some spin-glass features. These results are discussed in terms of the effects that might be produced by 4f--conduction-band hybridization, its modification by alloying and theories of the types of phase diagram that can be produced in itinerant-electron systems with competing interactions.
