The results of magnetostriction constant lambda(s) of multilayer Fe/C
sputtered films are reported. The measurements have been performed at
room temperature using strain modulated ferromagnetic resonance method
. The structure of films is amorphous, mixture of amorphous and cubic
and purely cubic. The magnetostriction constant lambda(s) is different
for any phases and depends linearly on the inverse of the Fe layer th
ickness.
