Abstract
Processes for coating substrates, in particular substrates including shielded surfaces, with iron oxide-containing coatings are disclosed. Such processes comprise contacting a substrate with an iron oxide precursor, preferably maintaining the precursor coated substrate at conditions to equilibrate the coating, and then oxidizing the precursor to form a substrate containing iron oxide. Also disclosed are substrates coated with iron oxide-containing coatings for use in various magnetic applications.
