“…Complexities in fitting the magnetic spectrum for the x = 0.60 sample made its value insufficiently precise to be included in this trend. The overall decrease in 8 with x is similar to that observed in FeAll-xCux [5] and is, we believe, attributable to the same cause whereby with increasing x the population of the 3d electrons around the Fe atom decreases reducing the shielding of the s shell electrons. The increased s electron density at the Fe nucleus as x increases produces the decrease in the isomer shift value 8.…”

“…The ferromagnetic phase arises for a Cr content of 0.4 < x < 0.5. Similar studies on the series FeAl, [5] determine that the ferromagnetic phase occurs for a Cu concentration of 0.25 < x < 0.325 while in FeA1, -,Fe, a ferromagnetic phase is observed forx = 0.10 [ 11 setting the limit at x < 0.1 for this series. Thus in order to produce a ferromagnetic phase progressively larger amounts of transition metal T are required as T changes from Fe to Cu to Cr.…”
