Granular F8.CLl1O0 . films have been r>rodtrced b':t a cluster beam (CB ) technictue. Sznall angleX-ray scatterung (SAXS) meastmretnents indicate that the geometrical size of Fe clusters is about5 nun in diameter for x = 13. IN/Iagnetization and magnetoresistance curves between 5 and 300 Kcan be fitted to the Langevin functions with taking accotunt of the Fe cluster size distributionand an inter-cluster magnetic interaction. The average magnetic cluster size estimated froraathese analyses is about 1.6 nm (180 atouns) for T >50 K, which is roughly consistent with SAXSobservation. However, smaller size distribution of abotut 0.6 nrn (10 atoms) is obtained frorn thesame analysis of the results at T : 5 K. This implies a rnagnetic size-down originated from amagnetic frustration at low temperattrre.
