Abstract

We have synthesized a series of nanostructured Fe/Ag composite metal films. The much enhanced magnetic coercivity was found to scale with the particle size which is process controlled. At a low substrate temperature(< 200°C), the film consists of small clusters of Fe(< 100Å) which behave superparamagnetically with a blocking temperature above 100K.
