New alloys of FexMo100-x over the whole composition range have been prepared by the sputtering method. It was found by X-ray diffraction that samples with 40≤ x ≤ 80 are amorphous, while the remaining alloys are single phase with the b.c.c. structure. In this paper, we report that a very high crystallization temperature Tcr of around 1100 K has been observed from the electrical resistivity measurements for amorphous FexMo100-x samples and that Tcr rises as the molybdenum content increases. After crystallization, the magnetic properties of these samples were studied using a vibrating-sample magnetometer. The results indicate that compositional dependence of the magnetic ordering temperatures Tc of these crystallized samples can be well described by the same equation as that for as-made crystalline samples, which is Tc(x) = 39 (x - 20)0.75 Also, further heating at high temperatures causes the segregation of α-Fe and molybdenum atoms.
