A method of producing magnetic metal oxide films bonded to an inorganic, non-magnetic substrate comprising the steps of applying a coating to the surface of the substrate, which coating consists of a very fine magnetic metal oxide powder dispersed in a suitable liquid. The applied coating and substrate are then heated to a temperature sufficient to evaporate the liquid constituent of the coating and form a thin, dense, magnetic, metal oxide film chemically bonded to the substrate. |
