Abstract : In the patent magnetic manganese ferrite and manganese-magnesium ferrite films of high compositional purity can be made by a relatively short and simple technique. The technique involves the dissolving of ferric nitrate and either manganese nitrate, or manganese nitrate and magnesium nitrate, in alcohol at room temperature; immersing the surface of a substrate in the solution; preliminarily firing the coated substrate at 400C to 700C and successively cooling to room temperature between coats. After weighing on a balance to determine exact amounts of material deposited, the coated substrate is fired at 800C to 1000C in an inert atmosphere for one to four hours to align the oxides formed to the spinel structure of the ferrite.
