Abstract
Thin films consisting of γ-Fe2O3 particles were prepared by a spin-on process using a solution of iron (III) nitrate dissolved in ethylene glycol. Film thickness was observed to be controlled by the solution viscosity as well as the revolution of a spinner. Local structures around iron ions in the solution were studied by extended X-ray absorption fine structure spectroscopy and the formation of an (FeO x ) n cluster was deduced. A film thus prepared was confirmed to consist of finely divided γ-Fe2O3 particles by TEM observation. Magnetic and optical properties of the films are briefly discussed.
