Hard Magnetic Films of Iron, Cobalt, and Nickel

Abstract Thin films of Fe, Co, and Ni were prepared by vacuum deposition. The angle of incidence was varied from 0° to 80° for the explicit purpose of changing the anisotropy and producing very high coercivities. The film thicknesses, determined interferometrically, were in the range from 100 to 4000 Å.
