Experiments to generate a thin composite Fe-Ag film employing a sputter-gas-aggregation process are described. The magnetic properties are studied at low temperatures. In addition, the morphology is determined by high-resolution transmission electron microscopy and the structure by using x-ray diffraction and XAFS. Small clusters of about 11 Å in diameter are highly dispersed in an Ag matrix. They show the characteristics of interacting superparamagnets.
