VIELSCHICHTIGER FERROMAGNETISCHER FILM UND VERFAHREN ZUR HERSTELLUNG DESSELBEN.

摘要

The film is composed of an alternate lamination of unit iron layers and unit layers of ferromagnetic iron compound such as Fe3Al, Fe3Si, Fe3Ge and Fe3Ga. The thickness of the both unit layers is less than 70 ANGSTROM . The film has a high saturation magnetization more than 230 emu/g and a high thermal stability so that the film is particularly applicable to a magnetic head core.
