Abstract: It has been found that vapor deposition of the ferromagnetic material MnAlGe onto a substrate will give a thin film having the easy direction of magnetization normal to the substrate. This unusual capability does not depend on epitaxial growth and, indeed, the preferred embodiment calls for the use of an amorphous substrate. This inherent property of MnAlGe makes it useful for the class of magnetic devices operating on the principle of the reversal of the direction of magnetization of isolated regions for the purpose of information storage.
