Measurements of the saturation magnetostriction lambda (100) on single crys
tals of Fe1-xGax with 0.21 less than or equal to x less than or equal to 0.
35 are presented. The temperature dependences of lambda (100) and the magne
tization of the x = 0.35 sample are discussed along with prior results in t
erms of a collapse of the magnetization into an inhomogeneous arrangement o
f iron moments (cluster glass). The anomalous behaviors of lambda (100) and
c(11)-C-12 vs. x seen in both Fe1-xGax and Fe1-xAlx alloys are attributed
to internal stresses associated with short-range atomic ordering. (C) 2001
