Title: Phase relationships in the CeFe 8 Co 3 Ti 1 - y Si y system

Abstract

We investigated the phase formation behavior of the nominal CeFe 8Co 3Ti 1-ySi y system for 0 ≤ y ≤ 0.6 by powder x-ray diffraction and scanning electron microscopy with energy dispersive x-ray spectroscopy for ingots formed by arc-melting then annealing at 1000 °C and quenching to room temperature. The ingots are seen to nearly single phase for y ≤ 0.4 and are multi-phase for y ≥ 0.5 though a compound of the ThMn 12 type does indeed form for all values of y. We also measured the saturation magnetizations (M s), Curie temperatures (T C), and magnetic anisotropy fields (H a) for the y ≤ 0.4 samples and the values of Ms and Ha appear to be nearly identical for all y 0.4. TC, but, is seen to increase about 20 °C in this range for increasing y.
