Free-standing block copolymer films containing magnetic iron oxide nanoclusters within the microdomains were produced by static casting. The thickness of the nanocomposite films was easily controlled to make optically transparent thin films. The size distribution of the nanoclusters was relatively narrow and the nanoclusters were uniformly distributed within the films. The spherical nanoclusters, ca. 5 nm in diameter, were identified as γ-Fe 2 O 3 and had a well-defined crystalline structure. Magnetic measurements revealed that the nanocomposite films are superparamagnetic.
