The forced volume magnetostriction of Fe-Al alloys in the concentration rangefrom 15 to 36.5 at %A[ has been measured at 4.2 K, 77 K and room temperature.The results were analyzed on the basis of a phenomenological theory of magneto-volume effects, where the volume change is classified into two contributions,the 3d band polarization and the volume dependence of exchange interactionbetween local moments. It is shown that the band polarization effect is dominantfor volume magnetostrictions in cluster glass alloys (AJ>30at%) as well as inferromagnetic alloys (Al< 30 at '%). The analysis gives a rough estimate of theintrinsic band susceptibility, which is strongly enhanced around the criticalconcentration for the collapse of a long range ferromagnetic order.
