Abstract

A method for fabricating a magnetic memory film is disclosed wherein an epitaxial layer of magnetizable material is grown on the surface of a substrate which has been selectively implanted to damage portions of the crystalline surface. The resulting polycrystalline portion of the epitaxial layer grown on the damaged substrate surface is then selectively removed to leave the monocrystalline portions of the epitaxial layer.
