Abstract :
The concentration dependence of the magnetic properties of amorphous Fe-P-B alloys obtained by splat-cooling is discussed. For a given Fe concentration, the magnetic moment 
averaged over all atoms of material and the Curie temperature Tc both increase with the substitution of B for P. We observed for the variation of and Tc as a function of the B content the same discontinuity as that occurring between the two phases 
and 
of the crystalline Fe3 P1-x Bx compounds. We studied also the variation of and Tc when one metalloid (P or B) substitutes for Fe, the other metalloid remaining constant. was found to decrease when the P (or B) content is increased, as expected from a rigid band model. For the same concentrations, Tc increases. The different behaviours of and Tc are tentatively explained by assuming that the amorphous Fe has two magnetic states (ferro and antiferromagnetic) as already suggested for crystalline Fe in a fcc environment.
averaged over all atoms of material and the Curie temperature T and T and of the crystalline Fe and T was found to decrease when the P (or B) content is increased, as expected from a rigid band model. For the same concentrations, T and TKeywords :
