The magnetic properties of Fe/Zr sputtered multilayers have been studi
ed as a function of the thickness of Fe sublayer (d(Fe)) from 6 to 300
K. For 0.7 < d(Fe) < 2.0 nm, both the magnetization at T = 6 K and th
e Curie temperature are found to be almost independent of d(Fe) with t
he average [M] = 700 G and [T-c] approximate to 170 K which seem to su
pport the supposition on amorphous structure of Fe sublayers.
