PREPARATION OF FERIII OXIDE-BASED THIN FILMS FOR OPTICAL AND / OR MAGNETIC RECORDING

摘要

The present invention relates to a process for the preparation of thin films based on Fe oxide. It consists in applying to a support a polymer composition of iron oxide prepared by controlled hydrolysis of an iron alkoxide solution. Hydrolysis is controlled by progressive release of water from a solution of the iron alkoxide in a hydrophobic solvent, from reverse micelles of water and a surfactant. / P P L ' The invention applies to the preparation of thin films by optical and / or magnetic recording. / P
